There is no Over Unity

[IronShell3d]

Hi NewBie123,

Simple question:

1) Ferrite domain alignment needs energy to overcome the Hysteresis loss, which by the way heats the ferrite both from the physical movement of the aligning domains and heats the ferrite due to the entropy alteration of moving from a random state to a ordered state. Placing a ferrite near a magnet will cause domain alignment and entropy alteration in the ferrite due to the influence of the magnets H field on the ferrite.

So where do you suggest the energy came from which caused the ferrite domain alignment to occur and altered the ferrite entropy from a random state to a ordered state?

If you have a vacuum tube full of electrons, you can't put a magnet next to it and watch electrons zip around in circles

Hi NewBie123,

What you never played with magnets next to vacuum tubes? You missed a lot of fun. Even better still was placing a magnet against a old colour CRT screen and watching the magnets field patterns displayed in colour on the screen. Try Googling "magnetron".

My question is still not answered. Why does the magnetic field density / direction need to change to cause copper atom to copper atom electron exchange and flow to occur?

Simple answer:

It comes from the power source that is moving the magnet,  which in turn is  causing the Fe magnetic moments (domains) to try to align.

I have before actually.

I thought I explained this already, but I'll try again....    If a magnet is just sitting next to a wire  (wrapped around the magnet, or whatever),  electrons (and whole atoms)  aren't excited or moving (other than their movement due to temperature), but a changing magnetic field will 'push' the electrons in one direction (or two directions for alternating directions) and create a current.    But the PUSH is what is required, not just a stationary magnet.

There is a "relative velocity" between the magnet and the electrons in the wire, but unlike the beam image in my previous post, the electrons are more stationary and the magnetic field is moving (the opposite effect).

Hi NewBie123,

Who said the magnet was moving? Stop thinking about motors as we are discussing a single isolated event.

That event is: does the H field of a stationary magnet cause domain alignment in a nearby stationary ferrite or not?

If it does cause domain alignment, then where does the energy come from that was needed to overcome domain alignment losses (Hysteresis losses) in the ferrite?

Second question which you have not addressed:

If we then release either the magnet or the ferrite or both, they accelerate toward each other and in the process do work and increase the kinetic energy of the moving item.

So where then does the energy come from that caused the kinetic energy increase in the moving items as they accelerate toward each other?

Note the acceleration increases as the distance between them decreases and the ferrite domain alignment become more complete. So here again more and more energy is sourced from somewhere and used to do work.
