A generator works on the principle of ______________

A generator works on the principle of electromagnetic induction. Electromagnetic induction is the process of generating an electromotive force (emf) in a conductor by varying the magnetic field around it. When a conductor, such as a coil of wire, is exposed to a changing magnetic field, it induces an electric current to flow in the wire. This current can be harnessed and used to power electrical devices or charge batteries. Generators typically consist of a rotating magnet or a coil of wire that spins within a magnetic field, creating a fluctuating magnetic field that induces an electric current in the wire coils.
