DC generator works on the principal of electromagnetic induction that when a coil is moved across a magnet so it experiences a force and rotates. It uses two full rings of copper called slip rings.

An electrical Generator is a machine which converts mechanical energy (or power) into electrical energy (or power).
Principle :
It is based on the principle of production of dynamically (or motionally) induced e.m.f (Electromotive Force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f. is produced in it according toFaraday's Laws of Electromagnetic Induction. This e.m.f. causes a current to flow if the conductor circuit is closed.
Hence, the basic essential parts of an electric generator are :
A magnetic field and
A conductor or conductors which can so move as to cut the flux.
