An inductor is characterized by its inductance, the ratio of the voltage to the rate of change of current, which has units of henries (H). Inductors have values that typically range from 1 µH (10−6H) to 1 H. Many inductors have a magnetic core made of iron or ferrite inside the coil, which serves to increase the magnetic field and thus the

An inductor''s electromagnetic energy storage manifests itself in the tendency to maintain a constant current through it.

Mathematically, energy stored in an inductor is expressed as. Where w is the energy stored in the inductor, L is the inductance and i is the current passing through the inductor. Ideal inductors have a noteworthy characteristic - they do not dissipate energy. This trait allows the energy stored within them to be harnessed at a later point in time.
