I guess its because I offer my services in industrial design and related
consulting, I get the question on magnetic motors quite frequently...
I always try to be very careful reminding people about the laws of
physics specifically thermodynamics that seem to have established quite
convincingly that there will always be more losses than gains ( I take the
time to remind people then that renewable energy harvesting is a
more promising investment of time )...

Anyhow I might try to explain that you can't use a magnet to attract
a heightened magnetic field, and then just somehow to be coerced to drop
that field and let some other magnetic power deliver the new superior
desire to turn in the same direction...
Completely impossible - and then to add something of value I might
speculate what if it ever could be developed could get a desired effect
like that? What if like an FET controlled with very little energy
investment something could influence instead of the flow of current the
'flow' of the magnetic field? What if a components para-magnetic properties
could be controlled? There might be physical difficulties but why shouldn't
it be possible to have a controlling voltage have superior effect over a
magnetic dielectric material ?

Any thought provoked were fully intended ;)
Let it flow, I want to know!
