BRAINCAKEA Dynamo
A dynamo is an electrical generator that produces a current. When a magnet in a dynamo spins, an emf is induced in the coil. If the coil is connected to a lamp, the lamp lights because the emf forces a current round the circuit. The direction of the current is given by Fleming's Right Hand Rule.
