Inductance
is the property in an electrical circuit where a change in the current flowing through that circuit induces an electromotive
force (EMF) that opposes the change in current. In electrical circuits, any electric current i produces a magnetic
field and hence generates a total magnetic flux Φ acting on the circuit. This magnetic flux, due to Lenz's law tends
to act to oppose changes in the flux by generating a voltage (a back EMF) that counters or tends to reduce the rate
of change in the current. The ratio of the magnetic flux to the current is called the selfinductance which is usually
simply referred to as the inductance of the circuit.
The term "inductance" was coined by Oliver Heaviside in February 1886. It is customary to use the symbol L for
inductance, possibly in honor of the physicist Heinrich Lenz. In honor of Joseph Henry, the unit of inductance has
been given the name Henry (H).  Wikipedia

Note: The prefix "ab" is used to indicate an electromagnetic unit in the centimetergramsecond
system. The prefix "stat" is used to indicate an
electrical unit in the electrostatic centimetergramsecond system of units.
