Self-induction. Faraday observed 1831 that on completing or breaking the current flowing in a helix an induced current is generated in a second wire wound outside the first. Henry showed 1832 that any variation in the strength of a current in a helix is also capable of inducing currents in the contiguous spires of the helix. The former is called MUTUAL Induction (q.v.). The latter is called self-induction, as representing the action of a coil on itself. It is also called Inductance. The coefficient of self-induction. L. depends on the coil itself, and is sometimes called its Inductance (q.v.). Since the quantity of electrification is proportional to the flow of force, (p, we may write 4>=1L, I being the current strength, or L=4&/L; i.e., this coefficient may be defined as the ratio of a flow of force to a current strength. Since the dimensions of

For practical purposes a Quadrant (q.v.) has been adopted. Since an ohm is a quandrant per second (10" C.G.S. units), an ohm-second, or a secohm (so called by Ayrton and Perry), is the equivalent of a quadrant. In U. S. the unit coefficient of self-induction is called a Henry. See Coefficient Of Mutual Induction.
