A 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.

Key terms in this lesson

Nuclear fission: The splitting of a large, unstable nucleus into two smaller nuclei, plus neutrons, releasing energy because the products are more tightly bound than the original nucleus.
Nuclear fusion: The joining of two light nuclei to form a heavier nucleus, releasing energy provided the mass number of the product is less than about 56.
