What is electromagnetic induction?

Electromagnetic induction is the process of generating an electromotive force (EMF) through a varying magnetic field.

Who discovered electromagnetic induction?

Electromagnetic induction was discovered by Michael Faraday in 1831.

State Faraday's Law of Electromagnetic Induction.

Faraday's Law states that the induced EMF in any closed circuit is equal to the negative rate of change of the magnetic flux through the circuit.

What role does Lenz's Law play in electromagnetic induction?

Lenz's Law states that the direction of the induced current will be such that it opposes the change in magnetic flux that produced it.

How does a basic generator work?

A generator converts mechanical energy into electrical energy by rotating a coil within a magnetic field, inducing a current via electromagnetic induction.
