Regarding Aromaz' comments about pulsing in magnets, here's an interesting comment from the Floyd Sweet VTA Yahoo Group
( Yahoo! Groups )
The poster quotes the info below as having come from another source. It seems to speak to the conversation here.
That said, I personally think there may be a more straightforward way to get the required magnetic fluctuations. But for what it's worth...

Thats what my friend did when he 'programmed' bubbles in
his magnets like Floyd Sweet did in his VTA (vacuum triode amplifier).
The bubbles are believed to vibrate enough to switch polarity very
rapidly but with very little electrical force....when it does the flip
in the presence of a wire...you get an induced current...do it fast
enough and you have power you can use.
I saw these bubbles with a sheet of the viewing plastic, held and tested
these magnets...regular identical ones had NO BUBBLE..and the ones he
programmed, you could clearly see the bubble...he said if you hit the
magnet or dropped it, the bubbles vanish but could be reprogrammed. And
the bubbles moved when you brought a magnet near them!
The process involves high voltage.
Using a bubble programmed magnet, Sweets VTA machine was 'tickled' with
a very low power output frequency generator...yet once the domains of
the bubbles flipped fast enough, he was pulling up to 1000 watts out of
this solid state device...see;

There are more but an immediate correlation to this is the Gary motor...see;

The domains in Figure 37 are oppositely magnetised and are thus
separated by a so-called "180* wall" in which the magnetisation vector M
rotates continuously by 180* from one orientation to the other.
In the bulk the axis of rotation is normal to the wall. This case is
called a Bloch wall. Note that in the centre of the Bloch wall M stands
perpendicular to the surface plane. This energetically very unfavorable
situation is avoided, if M rotates within the surface, i.e., the
rotational axis lies within the wall plane and normal to the surface.
This behaviour is said to be Niel-like. As a result, a bulk Bloch wall
takes a Niel-like surface termination. It should be pointed out that the
rotations of M in the Bloch- and Niel-like part of the wall are not
uniquely connected.
Experimentally, we may therefore observe a change of contrast along the
wall. This change of rotational sense of M is limited to the
near-surface region and forms a surface magnetic vortex (indicated by
the circles).
The width of the walls which are known as "V-lines" is found to be of
the order of 500 nm. These V-lines reflect a complex closure domain
pattern caused by the bulk magnetisation.
