Inductance (L) is the property of an electrical circuit whereby changes in current flowing in the circuit produces changes in the magnetic field such that a counter EMF is set up in that circuit or in neighboring ones. If the counter EMF is set up in the original circuit, it is called self-inductance and if it is set up in a nearby circuit then it is called mutual inductance. Fixed inductor uses multiple coils of a conducting material to store energy using a magnetic field. It belongs to the electromagnet family. The voltage produced is proportional to the rate of change in current flowing through it. The higher the number of coils and input current, the higher is the inductance
The unit of inductance is the Henry (H) and is the value of inductance in which an induced EMF of one volt is produced when the inducing current is varied at the rate of one ampere per second. The henry is commonly sub-divided into several smaller units, the milliHenry abbreviated mH, the microHenry abbreviated µH, and the nanoHenry abbreviated nH.
