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
