What’s a Dynamo?

A dynamo is an electric generator made from coils of wires that are made to turn in a permanent magnetic field by way of a commutator. Essentially any electric DC motor with a permanent magnet can become a dynamo. Rather than applying current to the motor to cause it to spin, you can turn the shaft of the motor and generate a current.
