The energy stored in the magnetic field of an inductor can be calculated as
W = 1/2 L I2 (1)
W = energy stored (joules, J)
L = inductance (henrys, H)
I = current (amps, A)
Example - Energy Stored in an Inductor
The energy stored in an inductor with inductance 10 H with current 5 A can be calculated as
W = 1/2 (10 H) (5 A)2
= 125 J
