Abstract
In this chapter, we discuss the electromagnetic induction phenomenon, starting from the discovery by Michael Faraday that when the magnetic flux linked to a circuit varies with time, an electromotive force, and its consequent current, appears in the circuit. We learn the differential equation ruling the phenomenon, namely that the curl of the electric field is equal to the opposite of the time derivative of the magnetic field. We discuss Faraday’s law under various circumstances and introduce the concepts of mutual inductance and self-inductance. Finally, we deal with the alternate current circuits and the impedances of their different passive components, resistors, capacitors and inductors.
