Inductance. In electromagnetism and electronics, inductance is the property of a conductor by which a change in current in the conductor induces a voltage in both the conductor itself and in any nearby conductors.
Inductance is measured using a unit called the Henry or H. Measure the length of the coil of wire in meters or centimeters. It's important to use metric units, since the Henry is based on the metric system. Determine how many turns there are in the coil -- i.e. how many times the wire is coiled.
