There is no Over Unity

The energy required to overcome frictional losses in the domains come  from the two objects coming together and accelerating toward each other.

Hi NewBie123,

The entropy change in a ferrite undergoing domain alignment / dealignment is called the "Magnetocaloric effect":

http://en.wikipedia.org/wiki/Magnetic_refrigeration

The ferrite's domain alignment is caused by the magnet's H field and not any motion between the ferrite and the magnet. Placing the ferrite near the magnet does not add energy, it actually reduces it as you reduce the magnetic potential. And so where does the energy that causes the moving object/s to gain kinetic energy come from?

Hi NewBie123,

Ok..  You meant magnetic entropy, not total entropy.  right?


Anyway,  the key to the magnetocaloric effect is a CHANGING magnetic field, not STATIONARY.  I believe this is the source of some confusion..     

And so where does the energy that causes the moving object/s to gain kinetic energy come from?

What do you think?
