What is the phenomenon called when a changing magnetic field induces an electromotive force (EMF) in a circuit?

Step 1: Understand that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 2: Learn that when the strength or direction of a magnetic field changes, it can affect nearby electrical circuits.
Step 3: Know that this change in the magnetic field can create an electric current in the circuit.
Step 4: This process of generating electric current from a changing magnetic field is called electromagnetic induction.
Step 5: Remember that Faraday's law explains how this induction works, stating that the induced electromotive force (EMF) is proportional to the rate of change of the magnetic field.
