Question
What do you understand by the term “electromagnetic induction”? Explain with the help of a diagram.
✓
Answer
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.
