Inductance

From Wikipedia, the free encyclopedia

Inductance is that 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 (See __Induced EMF__).

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 self-inductance which is usually simply referred to as the inductance of the circuit. The term 'inductance' was coined by __Oliver Heaviside__ in February 1886.^{[1]} It is customary to use the symbol L for inductance, possibly in honour of the physicist __Heinrich Lenz__.^{[2]} ^{[3]}

In honour of __Joseph Henry__, the unit of inductance has been given the name henry (H): 1H = 1Wb/
