http://www.thefreedictionary.com/inductance

Inductance

in·duc·tance
  (n-dktns)
n.
1. The property of an electric circuit by which an electromotive force is induced in it as the result of a changing magnetic flux.
2. A circuit element, typically a conducting coil, in which electromotive force is generated by electromagnetic induction.


inductance  (n-dktns)
A measure of the reaction of electrical components (especially coils) to changes in current flow by creating a magnetic field and inducing a voltage. Its unit is the henry.

Inductors

Inductance is typified by the behavior of a coil of wire in resisting any change of electric current through the coil.
Arising from Faraday's law, the inductance L may be defined in terms of the emf generated to oppose a given change in current:
