Inductance's 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 (See Induced EMF). In electrical circuits, any electric current i produces a magnetic field and hence generates a total magnetic flux Phi 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 r… (More on Inductance)
