Four pictures you'll understand what is inductor and how it works

The alias of the inductor is coil or reactor, which is a passive two-terminal electronic component with the nature of inductance.The process of release inductance as follow：

The current flowing in the coil generates a magnetic field, and then through the magnetic field of coils to produce the electronic current.

1, Coil turned into a magnet, Currents create magnetic fields.

2, Coil power generation, Magnetic field create currents.
Insert or remove the magnet, the coil current flows.

Making use of this feature, a variety of electronic components was born, this property has also been applied to the motor and generator.

3, Insert the magnetic core, Power up to the coil
Insert the core, and then it would produce a large number of lines of force。it comes from the ability to gathering magnetic field lines in the magnetic core. The ability to produce magnetic field lines is called inductance (L).

Inductance generation process

4, how to increase the inductance 
Increase the inductance of the methods are:
① increase the area of the coil loop;
② increase the number of coiling;
③ insert the core.
