The Field Magnet, Armature, Slip rings and Carbon brushes are the main parts of an A.C. dynamo. In a dynamo Electromagnetic principles are used to convert mechanical energy into electrical energy (alternating electric current). It consists of a Field Magnet, Armature, Slip rings and Carbon brushes. The armature is a coil that rotates between the two poles of the field magnet which induces a current to start flowing in the armature. Thus the rotational mechanical energy is converted into electric current.

The lights on a bicycle are powered by an A.C. dynamo. As the back wheel spins the friction driver rotates as a result of which the magnet starts to spin near the wire coil. Because of the change in the magnetic field, electricity is generated in the armature.

The first dynamo was built by Hippolyte Pixii in 1832. He also added a commutator that enabled him to convert the alternating current into direct current.
