Answer
Joseph Henry's main contribution to electromagnetics was the discovery of self-inductance. He found that a changing current in a conductor generates a magnetic field, and that this field can induce a current in the same conductor. This effect is known as self-inductance, and it is a fundamental property of all electrical circuits.
