In this lesson, we will review the concept of self inductance and introduce the concept of mutual inductance. Whereas self inductance is the induced voltage in a coil by current changing in that coil, the mutual inductance causes an induced voltage in a secondary coil in close proximity to a primary coil.
The concept of mutual inductance is central to understanding the circuit element known as the transformer.
