Hi supersam,

First we need to realize that most of the magnetic field that occurs in magnetic material comes from the intrinsic electron spins within the iron. So by moving a magnet to iron you are applying a magnetic field to the iron. This causes avalanche effects within the iron. An avalanche is usually millions of electrons flipping. Simply put you can think of the electron flip as a permanent magnetic that rotates and reverses direction. So within magnetic materials such as iron are countless tiny magnets.

When you move a permanent magnetic near iron you are applying a magnet field. This causes avalanches within the iron. These are electrons flipping, which generate electromagnetic waves. Nearly all these electromagnetic waves are absorbed by the magnetic material, but the coil hooked up to your speaker can pick up the faint signals.

paul,

thanks for the information.  i think i can now understand, why the current stops flowing when the magnet stops.  when you move the magnet away again i guess you just start the whole avalanche over again? or is this more like hitting the rewind button? 

sam

ps: i am guessing since it would be in a different "time" that it is like starting the avalanche again only in a different direction?

Hi supersam,

In iron or any electrically conductive magnetic material there are Eddy currents caused by a moving magnetic field such as the permanent magnetic, but this energy is infinitesimal compared to the magnetocaloric energy.  The eddy currents loop in the iron as the magnetic field moves due to induction. The magnetocaloric effect is similar except on a far smaller grander scale, but it is directly caused by the unpaired electrons within the iron and not the applied magnetic field. The permanent magnetic is the applied magnetic.

When you move the magnet closer the iron the spins flip to align with the magnet. These are the avalanches. When you move the magnet away the spins flip back to their original alignment.

I mentioned that nearly 50 megawatts of energy is exchanged in Gadolinium and roughly 25 megawatts for iron.

I notice that I made a mistake regarding iron. I forgot to consider that iron has a different heat capacity than Gd. Iron has roughly the same magnetocaloric energy exchanges as Gadolinium, which is nearly 50 megawatts in our example, not just 25 megawatts.

Of course these values are at near curie temperature. Since Gd is at curie temperature at room temperature and iron is not therefore Gd experiences far more magnetocaloric energy exchanges at room temperature. This is due to the Gd electron spins being nearly entirely randomized at room temp. where irons spins are in alignment within domains, but not in totality.

Ferrites containing MnZn should experience higher magnetocaloric energy exchanges at room temp. than say iron.

paul,
sounds to me like they would then be redy for another avalanche.
WATCH OUT!
