Inductor

An inductor is a passive electronic component dependent on frequency used to store electric energy in the form of a magnetic field. An inductor has the symbol

Inductance

Inductance is the characteristic of the Inductor to generates a magnetic field for a given current. Inductance has a letter symbol L and measured in units of Henry (H).

L = B/ I

This section list formulas for inductances in specific situations. Beware that some of the equations are in Imperial units.

The permeability of free space, µ0 , is constant and is defined to be exactly equal to 4π ×10-7 H m-1 .
