Inductor Basics

Inductor consists of wire wound around a core of ferrite material that includes an air gap. Inductor stores the energy in the form of the magnetic field. Inductor has many electrical properties when subjected to a magnetic field.

One of the important property of this inductor is whenever the current flows through the wire it creates the magnetic field around it. If we coil the wire , the magnetic field is stronger. When the electric current flows through the coil the magnetic flux will increase exponentially and stabilize at particular point, then stores the electric energy in the form of magnetic energy. When electric supply stops then the magnetic energy will decreases exponentially and turns back into electrical energy. By this we can say that it will temporally store the energy. The faster the change in the magnetic field the induced emf or voltage will be greater. To know about current and magnetic flux relation let us know Lenz's Law.
