Magnetic Fields: How Do They Affect Us?

01/06/2017 12:17 PM

The lower the operating frequency of a power line, transformer, switchgear etc., the more flux lines that are generated. Operating a transformer at 50Hz generates 20% more flux lines than at 60Hz transformer.

Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies are called electromagnetic radiations

By increasing or decreasing the magnetic field within equipment used on a daily basis, and exposing us to the frequencies and magnetic field, just how does this affect humans? For instance, how does this affect the thought process and decision making of people living with 50Hz as opposed to people living with 60Hz?

We are surrounded by varying frequencies daily in the west, from power supply, to cell phones, to internet, to naturally occurring lay lines and buried services as well as overhead services. There is no escape from frequencies.

Can living in a country with a lower frequency electrical supply affect how others see and understand the world? Those countries who have a very limited power supply, (or no electrical supply at all), and are far less exposed to 50 or 60Hz on a daily basis, do they have an even more adjusted/natural way of seeing the world?

"Those countries who have a very limited power supply, (or no electrical supply at all), and are far less exposed to 50 or 60Hz on a daily basis, do they have an even more adjusted/natural way of seeing the world?"

I'm considering a group of individuals who are, in general, probably exposed to very little non-natural EM radiation: Aboriginal Australians.

Do these individuals "...have an even more adjusted/natural way of seeing the world?" Dunno. Depends on your idea of a normal way of seeing the world. I'll bet that they believe my views are very much not normal.

Actually most Australian aboriginals are exposed to mains EM radiation from one source or another, i.e., the national grid or community-generated at more remote sites.

"In 2006, a greater proportion of people had access to the state grid for their electricity supply than in 2001 (28% compared with 24%), as more communities accessed this type of electricity connection (up 10%, to 204 in 2006). Community generators remained the main source of electricity supply for the majority of people (62%) in remote Indigenous communities in 2006. Very few people lived in communities with no organised supply of electricity (less than 1%)."

Well, okay...

Are there Polynesian islands, sub-Saharan localities, Arctic regions populated by Eskimos...

Must be somebody somewhere what don't never see no 'lectricity.

[Actually, I doubt very much that such a place exists]

Pretty certain there aren't many places where the ubiquitous AC 'hum' isn't present. It's a real pain in the arse for me because I do a lot of geomagnetic-related work down in the ELF band and AC hum does not diminish significantly with distance. The U.S. Navy, for example, operated their now-decommissioned Project Sanguine and Seafarer ELF sub transmitters at Clam Lake, WI and Republic, MI at 76 Hz with an EIRP of about 1 watt [at more than one megawatt input - antenna efficiency at these frequencies is extremely poor], yet were able to communicate reliably with submerged submarines worldwide. Russia has a similar system which operates at 82 Hz; ZEVS, located near Murmansk on the Kola Peninsula.

Compare with, say, the total installed electricity generation summer capacity in the United States which around 2013 exceeded one terawatt and you've got one hell of an ELF transmitter. A colleague in Finland, for instance, can not only detect the 60 Hz hum from North America's power grids, but can detect, from Finland, when various regions in the U.S. and Canada buy and sell power to each other.

Other frequencies besides 50 & 60 Hz are used in various places, though not on so massive a scale, but can still be a problem. Railways in Norway, Sweden and northern Germany still use 16 2/3 Hz (50/3 Hz). Railways in Austria, Switzerland and southern Germany also used to use 16 2/3 Hz but in 1995 switched to 16.7 Hz (no longer exactly 50/3 Hz). 25 Hz is still used by the southern half of the US Amtrak Northeast Corridor between Washington DC and New York City, the Keystone Connection between Harrisburg and Philadelphia PA, and by several nearby commuter railroads.

Probably the only areas on Earth where hum (both 50 & 60 Hz) is not a problem (at least for those of us whose work includes that frequency range) are the open ocean and remote polar regions well away from research stations and so forth. Otherwise it's a real pain the arse when you've an antenna sensitive to less than one picotesla and some bluddy transmission line a few km away whose emanations saturate the receiver's front end. Finding a place that does not have AC hum is next to impossible anywhere even remotely close to civilisation. Now, whether this poses a medical hazard has been kicked literally to death on both sides and I'm not about to contribute to the fray. I have my doubts but neither am I qualified to say either way.

Maybe 16.2/3 Hz is just below the threshold of audibility, eliminating the hum concerns (for most persons, anyway)....

Hmm....i can't hear what you are saying for that humming sound in my ears here in this power plant.

Seriously, it does affect me. When I get home, the first thing my wife says, usually sets me off into anger for some reason, never mind what she is saying, it is criticism, ridicule, or chiding me for not getting something done, even if it was not on the agenda, and she seems to wait until some news story has my full attention, or I am on my computer (laptop) attempting to analyze some 80,000 row by 20 column data set.

By the way, I think Excel tables do a fair job of making those long sets of data workable, compared to just regular rows. No one wants to sit around scrolling all night.LOL

Every been to work in Au? There are far fewer transmission lines crossing Au than you are told. There are SWER lines, (single wire earth return) at 20kv and most communities depend on gen sets or 22, 33, 66kv distribution lines.

Just as in Africa where they run 765kV lines, far fewer people are exposed to the amount of magnetic radiation than in the crammed overpopulated western countries. Au is only 44,000km² smaller than the USA and transmission is done at 132 and 275kV in most city areas. And just about each city area is located on the coasts. So they have less exposure than the US as much of the central regions of Au has no power lines.

Au is 50Hz, the US, 60Hz. Au has approx 48000km of transmission lines, the USA is more than 157000 miles, (251000km). If I have my figures correct, the US is more exposed to electrical pollution than most countries. It must have some affect on its 325,333,945 people. Au, 24 552 688 people and the tiny Brexitland has 65,382,556 people, running on 26500km of lines.

Curious!

You might want to research Bioelectromagnetics...

"Many behavioral effects at different intensities have been reported from exposure to magnetic fields, particularly with pulsed magnetic fields. The specific pulse form used appears to be an important factor for the behavioural effect seen; for example, a pulsed magnetic field originally designed for spectroscopic MRI, referred to as Low Field Magnetic Stimulation, was found to alleviate symptoms in bipolar patients,[5] while another MRI pulse had no effect. A whole-body exposure to a pulsed magnetic field was found to alter standing balance and pain perception in other studies.[6][7]"

"A strong changing magnetic field can induce electrical currents in conductive tissue such as the brain. Since the magnetic field penetrates tissue, it can be generated outside of the head to induce currents within, causing transcranial magnetic stimulation (TMS). These currents depolarize neurons in a selected part of the brain, leading to changes in the patterns of neural activity. In repeated pulse TMS therapy or rTMS, the presence of incompatible EEG electrodes can result in electrode heating and, in severe cases, skin burns.[8] A number of scientists and clinicians are attempting to use TMS to replace electroconvulsive therapy (ECT) to treat disorders such as severe depression. Instead of one strong electric shock through the head as in ECT, a large number of relatively weak pulses are delivered in TMS therapy, typically at the rate of about 10 pulses per second. If very strong pulses at a rapid rate are delivered to the brain, the induced currents can cause convulsions much like in the original electroconvulsive therapy.[9][10] Sometimes, this is done deliberately in order to treat depression, such as in ECT."

"While health effects from extremely low frequency (ELF) electric and magnetic fields (0 to 300 Hz) generated by power lines, and radio/microwave frequencies (RF) (10 MHz - 300 GHz) emitted by radio antennas and wireless networks have been well studied, the intermediate range (IR) used increasingly in modern telecommunications (300 Hz to 10 MHz) has been studied far less.[citation needed] Direct effects of electromagnetism on human health have been difficult to prove, and documented life-threatening interferences from electromagnetic fields are limited to medical devices such as pacemakers and other electronic implants.[11] However, a number of studies have been conducted with artificial magnetic fields and electric fields to investigate their effects on cell metabolism, apoptosis, and tumor growth.[12]

Electromagnetic radiation in the intermediate frequency range has found a place in modern medical practice for the treatment of bone healing and for nerve stimulation and regeneration. It is also approved as cancer therapy in form of Tumor Treating Fields, using alternating electric fields in the frequency range of 100–300 kHz.[citation needed] Since some of these methods involve magnetic fields that invoke electric currents in biological tissues and others only involve electric fields, they are strictly speaking electrotherapies albeit their application modi with modern electronic equipment have placed them in the category of bioelectromagnetic interactions.[citation needed]"

Yep I read that earlier, however these frequencies are not constant as 60/50Hz is constant, daily, 24/7/52, at home, in the office, work area, in the shops and restaurants, and not as sporadic as the range for low frequencies i.e. 0-300Hz range.

It seems that the 60Hz is a better frequency to live with, from what I have read.

It has been discovered that the general human healthy frequency is within the range of 62-72 Hz and when it drops to lower levels it enables the appearance of variety of diseases. For example at the level of 58 Hz, diseases like cold and flu were more likely to appear. On much lower levels (42 Hz) Cancer appeared in quite may humans.

Human Body:
Genius Brain Frequency 80-82 MHz
Brain Frequency Range 72-90 MHz
Normal Brain Frequency 72 MHz
Human Body 62-78 MHz
Human Body: from Neck up 72-78 MHz
Human Body: from Neck down 60-68 MHz
Thyroid and Parathyroid glands are 62-68 MHz
Thymus Gland is 65-68 MHz
Heart is 67-70 MHz
Lungs are 58-65 MHz
Liver is 55-60 MHz
Pancreas is 60-80 MHz

Colds and Flu start at: 57-60 MHz
Disease starts at: 58 MHz
Candida overgrowth starts at: 55 MHz
Receptive to Epstein Barr at: 52 MHz
Receptive to Cancer at: 42 MHz
Death begins at: 25 MHz

Do you want to clarify what you are trying to say with the list you gave here? You were talking about frequencies in the 50Hz - 60Hz range for earlier parts of this post, then all of a sudden these items all list MHz! That's 4-5 orders of magnitude change in frequency. And what are these the frequencies of? Nerve impulses? Makes me skeptical about whether you even know what you are talking about.

Original question: Can living in a country with a lower frequency electrical supply affect how others see and understand the world?

The list was simply an example and not taken as the gospel according to F Wit and presented as varying frequencies the body gives off and accepts as being able to sustain and handle.

As we as engineers know or make out to know on this site, frequencies are used to cure illness. MRI scans are quite common in use, but, one is not exposed to an MRI scans on a daily basis. Smart meters have been suspected of causing illness in people, we do know that power lines cause illness in people, cattle and crop growth is affected by the electro radiation so the same question stands for all the purported engineers on the site, does living daily with 50Hz or 60 Hz have any impact on the human brain or body, when we are exposed to it 24/7/52 and your entire life. And do the frequencies affect how we perceive the world, US 60Hz, the rest of the world in majority 50Hz. Nothing to do with Tfx designing, or switchgear or OHL or UG cable, just the frequency.

Maybe the answer is a Darwinian reply, our bodies evolved to cope over the last 130 years to deal with the constant frequency and we simply ignore the effects. Who knows, maybe 60Hz has an adverse effect on reading abilities or skeptisism or assumptions.

1MHz is 1 000 000Hz or 0.000050Hz. The question is quite clear and plausible. And I guess from here so far, it is like global warming, no one knows for sure.

"1MHz is 1 000 000Hz or 0.000050Hz'

No, 1 MHz is 1,000,000 Hz. Period.

0.000050 Hz is 0.000050 Hz, or one cycle every 20,000 seconds (5h 33m 20s). Period

They differ by a factor of 20,000,000,000.

Yes I've seen a lot claims, but no proof of concept...this seems like pseudoscience poppycock to me...If this were true people exposed to certain frequencies would all have the same diseases and people exposed to others would be geniuses...Does that seem even remotely possible to anybody who isn't selling something....? No I don't think so....now I do have some crystals that are guaranteed to cure what ails you for a very reasonable price, considering....

Vibrational Frequency List

In 1992, Bruce Tainio of Tainio Technology, an independent division of Eastern State University in Cheny, Washington, built the first frequency monitor in the world. Tainio has determined that the average frequency of the human body during the daytime is 62-68 Hz. A healthy body frequency is 62-72 Hz . When the frequency drops, the immune system is compromised.

Human Body:
Genius Brain Frequency 80-82 MHz
Brain Frequency Range 72-90 MHz
Normal Brain Frequency 72 MHz
Human Body 62-78 MHz
Human Body: from Neck up 72-78 MHz
Human Body: from Neck down 60-68 MHz Thyroid and Parathyroid glands are 62-68 MHz
Thymus Gland is 65-68 MHz
Heart is 67-70 MHz
Lungs are 58-65 MHz
Liver is 55-60 MHz

Colds and Flu start at: 57-60 MHz
Disease starts at: 58 MHz
Candida overgrowth starts at: 55 MHz
Receptive to Epstein Barr at: 52 MHz

hahaha...

..."All the stuff about frequencies is of course complete nonsense – human bodies and essential oils do not in fact have characteristic frequencies, nor do they broadcast radio waves in the VHF (30–300 MHz) band, nor is there any association between frequency and disease (individual chemical bonds within molecules have characteristic frequencies, in the infrared or visible-light range, but that is not what is being discussed here). Scientific words are being used here in a nonsensical way, in an attempt to give credibility to the associated medical claims. The link to Eastern Washington University is being used in the same way. In fact, Eastern Washington University does not even have a Department of Agriculture (so that the late Bruce Tainio could not have headed it), nor is the company founded by Tanio mentioned on the university’s web site at all. But yet, inexplicably, people seem to believe this stuff. Why?"

It appears that the device used to get these values was the BT3 Frequency Monitor.
The device is no longer available, but some sales propaganda and some datasheets are available here:

In the same transformer, varying the frequency from 60 Hz to 50 Hz increases the flux. This is because flux is proportional to current and the inductive impedance of the transformer increases with frequency. Therefore, the current in that same transformer decreases as the frequency is increased.

You can't compare a transformer designed for 60 Hz in the USA with another transformer designed for 50 Hz in another country.

And not 60 kHz with its IRIG H modulation format also? That's the best of the bunch. (hint, hint)

I've been trying to find a "kit" so I can build a receiver for that.

I'll look into that. I thought the C-Max chips were no longer made.

My girlfriend was concerned about three transformers they placed across the street. I did a little research and found we were really getting zapped by the coffemaker in our kitchen.

"Distinguishing between reality and appearances is something that is done by everyone on a daily basis. Whether it is looking at the rainbows in the sky or watching a person perform a magic trick, people constantly discern between what is real and what appears to be real. In general, appearances are more likely to be misleading when compared to reality, which exists regardless of whether or not it is observed by someone.

According to Plato, knowledge is of reality and opinion relates to the appearance of reality. The ways in which people makes sense of the world around them comes from a combination of appearances and reality. Furthermore, Einstein's theories of relativity and advances in quantum mechanics have led some scientists and philosophers to claim that the entire universe and three-dimensional space that people perceive as reality may simply be an appearance as opposed to something that exists independently from the observer."

from here. Two persons in the same environment would have a different idea about the reality. What possible option to you see to distinguish this from the effects of magnetic field lines?

A1) -

A2) Does it cause them to make major misjudgements in election events?

A3) -

A4) The Swiss railway network runs at 162/3Hz. It would be unfair to leave the Swiss out, even if they chose to stay out.

They used to use 16 2/3 Hz but now use 16.7 Hz:

"The first generators were synchronous AC generators or synchronous transformers; however, with the introduction of modern double fed induction generators, the control current induced an undesired DC component, leading to pole overheating problems. This was solved by shifting the frequency slightly away from exactly ⅓ the (50 Hz) grid frequency; 16.7 hertz was arbitrarily chosen to remain within the tolerance of existing traction motors. Austria, Switzerland and Southern Germany switched their power plants to 16.7 Hz on 16 October 1995 at 12:00 CET."

Aw, what's 0.03333333333333Hz between friends, eh?

I know, right. One additional cycle every thirty seconds? Boy that's really pushing the envelope.
