electric motor

This is an electric motor that can be made quite easily

adjust the positions of the switch and the coil until the motor goes on turning when you spin it. Reed switches damage easily and a partly-working switch will stop the motor working. If the motor is run without the capacitor the switch will arc in a very satisfactory way for a few moments and then stop working or even worse work only intermittently. The problem is minimised if only one battey is used but the motor works much better with more batteries.
If the coil is made with a ferrite core it will work much better, although it can be made to work with a few turns of insulated wire round a nail. This is almost a short circuit.
