Generation of Electricity

12/13/2010 12:20 PM

According to Farday's law of em induction (changing magnetic field linked with a coil) electricity is generated. What about superconducting gas flowing in a conducting pipe under magnetic field? (it follow the principle and generate electricity) hit.

There will be no magnetic field inside a conducting pipe, therefore the electricity generated will be zero.

Perhaps you are thinking along the lines of magnetohydrodynamics:

A superconducting gas?

You have no idea at all about the present understanding of either solid (superconducting) or gaseous state Physics. You seem to only know the words to some electromagnetic theory. Instead of attempting to generate an interesting question, just ask us about what you don't grasp on electromagnetics.

MHD works but why its not used? Thanks for the offer refered.You guys wont give a straight answer if its asked.I wonder the forum is designed for intellectual giants. Or is it you derive pleasure from it when you say do your homework. Or you feel awkward after answering. But its always an inspiration to know some guys are very tech-freaks.

Ok, MagnetoHydroDynamics, the Massachusetts Highway Department, and a Micro Hybrid Drive have nothing to do with a gas or superconducting. What are you talking about?

I didnt get a classmates like you guys but it doesnt mean you replace the guys i already had. In case i would have become a moron,philosopher or head-strong maniac. Cya

"superconducting gas flowing in a conducting pipe under magnetic field"

There would be no voltage induced between where the conducting pipe entered the magnetic field and where it exited the magnetic field.

If the superconducting gas crossed the magnetic lines of force, there would be a voltage induced in the superconducting gas.

The superconducting gas would be short circuited by the conducting pipe.

This short circuit current would remove material from the conducting pipe.

If the short circuit current continued for a long enough time, it would make a hole in the pipe.

YOU PEOPLE SURE ARE HARD ON SOMEONE ASKING A SERIOUS QUESTION.

I hope if I'm incorrect no one lynches me. Please

A superconductor shorts out any resistor in parallel with it. By Lenz's law there will be no magnetic field inside a conductor.

I know of no condition that there can be a superconducting gas. For super-conduction to occur the electrons flowing (aka current) on the atomic scale must be constantly and immediately be replaced by another electron entering. This is reflected in Kirchoff's current law. If in moving the electrons the nucleus gets jostled from any temporary field imbalance then the nucleus gets accelerated in some random direction, heating occurs. If heating occurs then super-conduction is not happening. In a solid the distance between atoms gets small enough that Quantum Dynamic Effects do cause instantaneous transfer of electrons. A gas by definition expands to the volume available to it. The average distance between atoms is not so close to zero that QDE cannot transfer electrons from one atom to the next instantly. Ions then accelerate and heating occurs.

Yes, I can get a bit strident when fantasy interacts with Engineering. Particularly when my work is dealing with that type of Engineering at the moment that fantasy appears. Please read my other reply why the OP question is pure fantasy.
