Electrical Studys

To understand what is inductor, we should know the term self inductance.

When a current through a conductor,the conductor creates a magnetic flux proportional to the current flowing through it. So, when the current flowing through a coil changes, a time-varying magnetic field is generated automatically inside the coil, & according to Faraday’s law of electromagnetic induction, a voltage is induced in the coil as the law states that, the induced electromotive force in any closed circuit(here the coil) is equal to the rate of change in the magnetic flux through the circuit.

In electrical dictionary, this particular phenomenon is called self inductance property.

So, which electrical element shows this property, called as an inductor.

The sign of an inductor is like :

The another property of an inductor is it can store energy in its magnetic field.

A real inductor looks like this:
