Inductor Energy Storage Calculator
Ideal linear constant inductance: E = LI²/2. Signed current gives the same energy; inverse current has two signs except at zero. Excludes saturation, losses, tolerances and current ratings.

GOOD TO KNOW
Common questions
Does this select or rate equipment?
No. The ideal model cannot determine safe ratings or real equipment behavior.
