My very own simple motor

Although I had learn this in my Secondary school days, this is the first time I tried it. I think it works pretty well :)

  • coil of insulated wire
  • paper clips for support
  • magnet
  • batteries and wires
  • a base to mount everything

Note: you need to strip HALF the insulation at the ends of the wire.
