So it's still just axially magnetized? I made a crude flat voice coil(round magnet wire doesn't like to stay put) and couldn't get it to attract/repel a neodymium magnet at the center of it. It would only attract/repel towards the ends of it, like a linear voice coil, so I incorrectly figured...
I know that a linear voice coil is polarized from top to bottom, but how is a flat coil polarized? Would a flat coil be polarized from the inside to the outside? Where the inside(blue) is one pole and the outside(red) is the other? If you were to do multiple windings(stacked layers) would it...
