## Energy Stored in an Inductor

The energy stored in the magnetic field of an inductor (links to http://www.mw0llo.com/inductors.aspx) that is passing a steady electric current is given by:

$E=0.5L{I}^{2}$ | E = 0.5 LI^{2} |

Where:

E = energy, Joules

L = inductance, Henrys

I = current, Amps

Energy, E =
