What do you understand by the term electromagnetic induction? Explain with the help of a diagram.

The production of electricity from magnetism is known as electromagnetic induction. Let us move a wire $AB$ upward rapidly between the poles of the horseshoe magnet. When the wire is moved up, there is a deflection in the galvanometer pointer which shows a current is produced in the wire $AB$ momentarily. Thus as the wire is moved up through the magnetic field, an electric current is produced in it.
