A coil of wire is connected to a galvanometer.When the coil is rotated in a magnetic field,the galvanometer records a current because the free electrons in the moving wire experience a force from the magnetic field that pushes them through the wire.

Question

Quizplus · Accepted Answer

This is the principle behind the working of an electric generator. When a coil of wire rotates in a magnetic field, a current is induced in the wire. This is called electromagnetic induction. The force that pushes the electrons through the wire is known as the Lorentz force. The Galvanometer helps to measure the magnitude of the current induced in the wire.
