Actually, I've tried this before, with a bell, and it worked. The strip is
flexible enough that the steel plate whacks the electromagnet with enough
force to nudge it along. When done very quickly, it looks like it's
vibrating. It's really neat, but also somewhat unpredictable, as the bell
will go off on a tangent=8Bliterally. So don't flame this, because it isn't
going to levitate, it's just going to kick itself along. Like Mark Tilden's
Magbot which has the magnet scooch along underneath, and then pulls itself
forwards. This is just a bit more controlled, and can make an annoying
ringing sound all the while =3D)
