Electromagnetic induction is a process whereby an electric current is generated within a conductor by changing the magnetic field around it. When a magnetic field is moved past a conductor, the magnetic field induces an electric current in the conductor. This is due to the fact that a changing magnetic field produces an electric field, according to Faraday’s law of induction. This electric field then drives the electric current. The magnitude of the induced electric current is proportional to the rate at which the magnetic field is changing.
