1. Cut (2) 11" strips of paper about 1/2 wider than your neodymium magnet is tall. A cutting board works best. Wrap one piece of paper around the magnet and secure it with tape.

TIP: Be sure you don't tape the paper to the magnet. Only to itself.

Then wrap the other piece around the first and secure it with tape.

TIP: Be sure you don't tape the second band to the first, only to itself to secure it.

Is it ok if you use conducting wires?

I have tried this one. It worked. But, sound level is too low . It was more like a earphone in a large scale. Is there any way to increase the sound level.

*Did you wind the coil layer by layer or it was just a rough winding ?

Please let us know about the winding technique. May be others are waiting for this....

Would electrical tape have any affect on this project instead of clear tape?
