Anyway, seems to me that there is "free" energy in
permanent magnets in the form of static B-Fields
eminating from the magnets... providing limitless
magnetic induction fields. Now the magnetic energy
varies as the square of the magnetic induction (B).
So.. the work (W) can be calculated by integrating
B^2 /2*uo with respect to volume 't' (where the B-field
is not zero..) Now the question I have... is this work
must be time dependant so that the B-Field has to
vary in time.. or the intergrated volume has to change
in time. The magnets then.. either have to be time
varying (oscillating B-field) or rotated in time... to
extract energy. The question then becomes.. do we
spend more energy rotating this field or volume than
we can get out of the "free" B-field? The magnets
must be dynamic and not static therefore... Too bad
that permanent magnets do not have oscillating B-Fields
or we would be SET!!
