Inductor Definition

1.1 An inductor (also choke, coil or reactor) is a passive two-terminal electrical component that stores energy in its magnetic field. For comparison, a capacitor stores energy in an electric field, and a resistor does not store energy but rather dissipates energy as heat.
Any conductor has inductance. An inductor is typically made of a wire or other conductor wound into a coil, to increase the magnetic field.

When the current flowing through an inductor changes, creating a time-varying magnetic field inside the coil, a voltage is induced, according to Faraday''''''''s law of electromagnetic induction, which by Lenz''''''''s law opposes the change in current that created it. Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents.

1.2 Inductance coil :Increasing current in a coil of wire will generate a counter EMF which opposes the current. Applying the voltage law allows us to see the effect of this EMF on the circuit equation. The fact that the EMF always opposes the change in current is an example of Lenz''''''''s law. The relation of this counter EMF to the current is the origin of the concept of inductance. The inductance of a coil follows from Faraday''''''''s law.
