The current needed to release the magnets is indeed smaller than that needed to repel them, but the resulting torque should be proportionally smaller as well.

Someone once said, 'a little bit is infinitely more than none at all.

Also, there is no repulsion.

No, that's not what I meant to say. What I was trying to convey was the point that
- yes, you can detach a magnet that is attracted to an iron core by supplying just enough
current to the coil to 'cancel out' the permanent magnets attraction and allow it to drop off.
- in most electromotors the current is usually increased above that point which does generate
a repulsive force, and this provides additional torque in the rotor
- in your idea this does not happen, so although the attraction is cancelled out, the
torque generated should also be a lot less than in a motor that does generate repulsion
- so the energy you save on the input side by not generating this repulsion also leads
to less effective torque on the output side. Less in => less out.

That was sort of what I meant to say.

It's still a nice idea and I don't want to be negative, I'm just telling you what I think will happen...

Okay, looks promising. What are the test results? Does it produce OU and why? Many devices are built in the computer, but without any pactical application it is just digital air. You have to start building the thing.

Just an idea: The purpose for the coils is to break or as you put it fade the point of highest flux density to get over the sticky point. In order to do this, you must generate a magnetic field equal to or in excess of the permanent magnetic field to effectively break the attraction. Conservation of energy aside, this principle won't scale very well. A larger wheel with larger magnets will require more energy in the coil to have the same effect. There are lower energy methods to neutralize or reverse the field. Look up Wesley Gray's work and also look at Steorn's low energy actuator. Using an actuator on a slide or small wheel, you could reverse the polarity of the magnetic field and get twice the effective torque. Not just break the hold but convert it to a push.
