- n. The ratio of the electromotive force produced in a circuit by self-induction to the rate of change of current producing it, expressed in henries. Also called coefficient of self-induction.
from The Century Dictionary and Cyclopedia
- n. Inductance due to interlinkage of an electric circuit with the lines of force of a current flowing in the same circuit: distinguished from mutual inductance, where the interlinkage is with lines of a current in a second circuit. See inductance.
- n. The numerical value of self-induction; the coefficient of self-induction. See inductance and unit of inductance.

Sorry, no etymologies found.
The correlation between mutual inductance and self-inductance results from the equations (5.13) and (5.15.) with L = N2/Rm we have M2 = k2L1L2
The latter equation indicates that, in a current-carrying coil, an electromotive force is induced by the magnetic flux associated with the current in the coil; the magnitude of the electromotive force is proportional to the rate of current change DI/Dt. The proportionality factor is called inductance L (more precisely self-inductance).
Laws of induction, self-inductance, mutual inductance.
Henry observed a large spark that was generated when the circuit was broken, and he deduced the property known as self-inductance.
The result is that today Faraday is recognized as the discoverer of mutual inductance while Henry is credited with the discovery of self-inductance
