Yes, but neodymium magnets are best because they are strong, and the stronger the magnet, the faster it spins.

Question

Is it necessary to use bare copper wire?

Community Answer

Yes. An insulated copper wire won't establish contact with the terminals and the circuit won't be completed.

Use non-insulated copper wire. Also, avoid braided wires. Other than that, they all should work.

Question

Can I use other types of copper wire for this?

Community Answer

Yes, but it must be able to pass electricity through it easily. Basically, almost any wire that is metal should work. And if it doesn't work, immediately take off the wire from the motor to make sure your battery does not burn.
