If you don't have an old speaker you can use to experiment with, visit
the next local swap meet. I'll be interested in knowing how well it
worked for you.

Does this mean it might work?

I'm not too sure that wire wrapped around a magnet would be that great
at picking up electromagnetic waves - honestly.
I could be wrong, but it doesn't make a lot of sense to me really.
removing the magnet would result in better reception, but the length of
the wire in the voice coil probably wouldn't be nearly enough anyway.
