I worked under two managers, Honours, that where successful, and in the process had the early version of the mobile phone in their car. They both died young with a brain tumor. So who knowns?

There are no documented effects. There are anecdotal reports of cancer, disorientation, etc. I believe EPRI looked at this and said "No" and one of the Scandinavian authorities looked at it and said "Probably". I think you would have to specify intensity and frequency to even ask the question.

Dear All,

Keeping apart the ill effect of Mobile use (excessive) on human body , there are certin existing and developed megnetic therapies (Where magnet is used in some form) and which are applied in curing certain diseases by doctors in certain countries.

So Magnet does have an effect on body, but how much exposure and what strength will effect our body in good and bad way could be debatable.

Here's one!

"'This, my dear," said he, impressively, "is the wonderful Love Magnet. It was given me by an Eskimo in the Sandwich Islands--where there are no sandwiches at all--and as long as I carry it every living thing I meet will love me dearly.'"

Well, if you were stupid enough to build an electromagnet that could handle the current produced by any nuclear power plant, it is possible to pull the iron out of your blood, though the flesh and bone of your body. What the effects are? I have no idea, but I would be willing do document it with a telephoto lens on my camera, and even help design the magnet if you really want to know.

Truth is, no one knows. And since you were born in and will die in magnetic fields, you may never know. But if you could, you could probably defy gravity as well. Since you have a propencity to believe this...I do have some beachfront property in Arizona I can sell you...or it will be in the next 100-1000000 years...buy early, avoid the rush...

Velocity, energy, magnetism, mass, gravity...are they really all that different?

Hi, rakheebhat !

Interesting question. Quite probably, since our species evolved in a magnetic environment, some of the functions of our anatomy are directly related to its presence. Some believe that migrating animals, fish and birds have a built-in magnetic compass.

The earth, in addition to an atmosphere, possesses a magnetosphere, which is the sum total of the magnetic lines of force about the poles; and as the earth flies through space, many of the otherwise harmful short and long interference waves are transported along these lines and admitted at the poles, causing the Aurora Borealis, or northern and southern polar light displays.

While still in the realm of superstition and snake-oil salesmen, magnetic therapy or the application of magnets strategically placed on the human body has begun to find acceptance in modern medicine; and is used to encourage more rapid healing of broken bones. Acting as my own snake-oil guy, I bought a magnetic bracelet; and though I make no claims about its effects, I have been waking up in the morning without back pains since very shortly after I began wearing it.

Man-made, or electro magnetic force (EMF) is taking a lot of heat for being a cause of cancer; and the statistics seem to support that certain cancers in children -especially brain cancers- who live in close proximity to overhead power lines or whose beds back into wire-filled walls have a higher occurrence rate than children who live more remotely from EMF sources. Cell phones are also in judgement limbo about radiation effects they may have on the users' brains; although which kinds of radiation are at fault is not known (it may be something other than EMF), and the manufacturers are doing everything they can to minimize all types of radiation from their handsets.

Historically, magnetism as a navigational aid, motive force (motors), and in communications technology has opened up the world to its inhabitants. This means a broader range of civilizations being now able to communicate with one-another. Newer developments employing magnetism in this area include super magnets that improve the transmission of various energy forms and can be made to work against each other to produce levitation.

The result of this communication on the human body has been the development of new medicines, biological research, diagnostics tools (not a few of which are dependent upon the properties of magnetism), and healing approaches; the ability to transport those in need of emergency or emotional assistance to important destinations; and the enormous savings of time in just getting around. Magnetic containment is being used to attempt to create hot fusion, a potential new energy production source.

On a service scale, we humans who employ magnetism use it to travel both horizontally and vertically, shave, clean our teeth, cut our hair, make our clothing, freeze, cook and prepare foods, even clasp lids on, and hold notes on the refrigerator. Trades use magnets to hold fasteners onto drivers. People dealing with small parts can pick them out of difficult spots with magnets, and children can fish for coins that have fallen down sidewalk gratings with them.

As I look around my home, I see hundreds of magnetic applications designed to make my life easier and more interesting. And I guess it helps that I'm a gizmo junky. Maybe all the EMF floating around here will cause me to die sooner, but before that happens, I'll probably live longer because of the conveniences my gizmos offer me; so those opposing forces seem to even themselves out.

We've evolved on, grew up with, and live inside a great big magnet, and our civilizations have become almost totally dependent upon magnetism and the useful properties we have noticed about it.

And that's a lot of "effect of the magnetic field on the human body."

The magnetic fields probably do affect us, then.

A Swedish researcher has linked cell phones to a 50% increase in salivary gland cancer. I'm not sure how they did that study. It was mentioned on Science Blog.

MarkTheHandyman,

That was a great answer, and I marked it as such, however on one little point, I always thought that coins were non-magnetic "and children can fish for coins that have fallen down sidewalk gratings with them." Thinking perhaps I am wrong, I fished about in my cash register with a magnet and got nothing. Maybe my coins are defective. I know they don't buy as much as they did years past.

And Mark always wondered why he had a pocketful of 1943 pennies.

Hi, Techart!

Growing up in Canada, I was privileged to be able to have change made partly of magnetic metals. If you couldn't use a magnet, what other devices did you employ to get at that change? I know kids are inventive.

Bubble gum on a stick

Ah hah, we were both right, different allloys for coins. Just checked some other country's coins from my coin collection. Wonder if US is just too cheap to use better stuff or if there is a real reason we don't use what other countries do? Or maybe we ......On second thought, never mind. It was too stupid an idea to write.

Thank you for your excellent explanation I really appreciate it.

Hi Mark,

"While still in the realm of superstition and snake-oil salesmen, magnetic therapy or the application of magnets strategically placed on the human body has begun to find acceptance in modern medicine;..."

I think we should get some leeches, feed them magnets, then market them to the medical community.... Just so KrisDel™ doesn't get to it first we need to copyright the idea, something like "Magleeches for medicine©" or some such.

Whatdya' think?

If you want a thorough information on magnetic field effects on human body , then read following book : "Cross Currents" by Robert O. Becker. You will find book in amazon.com. We created machinary to disrupt magnetic fields in nature. Its equivalent disrupting air quality with manmade gases.

feet represents SOUTH pole and head represents NORTH pole.so magnetic lines travel from feet to head.

While sleeping feet should point north and head should towards south.

Improper sleeping causes ill effects.


To recover any pain in body a proper magnet is used at that place .Magnet attracts RBC from blood.

Recommend you Google the subject. I recall reading a recent medical article on the subject on a medical news release website.

With all the magnetic fields we create and all the other "harmful" things we are doing, it's always interesting to remind everyone that just 100 years ago, the average life expectancy was in the high 50's. 500 years ago, it was in the low 40's. Now, it's in the high 70's, yet everyone thinks we're just killing ourselves. Of course we're going to die of a multitute of new and exotic diseases. We now know what's killing us. A few hundred years ago, the only things you died from were injury, sickness and old age. Doctors have a few more options now.

I long for the old days...

"Doc, why'd he die?"

"Because his heart's not beating" Badum beeeeeeeeeeeeeeeeeeeeeep

In Australia there have been several studies on the health effects of Electro Magnetic Forces (EMF), both mobile phones and transmission lines.

None of them seem to have come up with anything conclusive. I have worked for many years in the power industry and have always thought that if the effects would be most clearly seen in those that were exposed at a very young age, that is growing up under a power line or exposed to very high field strengths such as those who work around large generators or the transmission side of the Power Station.

Neither seems to have caused a worth while statistical blip.

The human body does interact with electrictromagnetic fields, ask anyone that has had to adjust a TV aerial, and I for one would expect that this would have some effect on the body. Probably not good, but at least measurable. So where is the accumulated evidence?

As mentioned earlier in this discussion, the earth has its own magnetic field and this is very useful for lots of reasons one of which is that the magnetic field tends to protect us from stray space EMF by channelling it to the poles. Could this also apply to the human body? If we have an electric field around us would this not tend to deflect adjacent fields of both the magnetic and electrical types?

BAB.

There has been exhaustive research on the potential for elevated cancer risk in electrical workers, which as a study group present the greatest exposure to EM fields. As many studies as have been done, there is no conclusion that anyone can agree upon. Some studies did show an elevated risk of leukemia, but there was no way to directly link it to the EM fields because electrical workers are exposed to a lot of environmental hazards including carcinogenic chemicals.

One study I recently read attempted to draw a direct line to EM fields in their conclusions. But when the source of the data was revealed, it turned out to come from Aluminum Smelters and the scientists were assuming the cause was EM field strengths because they were so extreme compared to other industries, But I have been to many aluminum smelting plants and I can attest that they are nasty environments in terms of fumes and chemicals. I would be surprised if anyone lives long after working there for any length of time.

I live in a neighborhood where 500kV power lines run right above and behind my house. My radio and TV reception is affected so I know it is relatively strong. But I have lived here 11 years and I have neighbors who have been here since 1970, yet NOBODY in this entire neighborhood has died of or been diagnosed with anything unusual. I think the entire affair is overblown.

Small doses o poison are medications - middle are in our food - high can kill.

The same in radiation. And maybe with herbs.

Why EM fields do not act the same way? Think about MRI vs. microwave ovens.

I did work in one institution where Maxwells / Gausses were measured and screen installed.

You have to know the difference between constant (or very slow-changing) magnetic fields like those given by permanent magnets, including the Earth, and AC-generated magnetic fields.

Apparently, low-intensity constant magnetic fields are having good effects on humans, while AC magnetic fields such as power lines' are doing some harm, especially when the exposure is long. Maybe the changes induced in any living creatures by magnetic fields are evolving so slowly and incrementally that is hard to detect them objectively.

I am sure that a lot of scientific research has been conducted on this topic but high interests are blocking any publishing. We are trapped by the price for our technology to continue running and bring profits and sometimes the price is measured in human lives and sufferings. Energy and telecommunications companies are making the rules.
