Cool.

I made a magnet-less speakers, using a speaker that didn't used a magnet, made two windings, working in opposite phase to make the voicecoil move.

I find it hard to believe though that it's about the same efficiency than a parmanent magnet type, because the magnets nowadays are unbelievable strong and this is 'free energy' I'll dig into it a bit deeper when i get back from work. If it is the case; nice piece of engineering.

They won't have got as much torque in a little can such as an RC motor with a permanent magnet though.
