Motors

Copper is not magnetic and we use it because we can start it and stop it by applying a electric current if we were to use a iron we could use it and have no need to create a magnetic field around it because it is already magnetic but once we start it we could never stop. The motors we made are built using a battery a neo demian magnet and a copper wire, the motor work because when you put together the circuit the copper wire gets magnetised and if you have it just right a perfect balance between touching the magnet and not getting a lot of friction the motor will start going because the magnet is pushing the copper wire forward every time it has the chance to this makes it spin.
