Inductor Energy Calculator

How Inductor Energy works

For Inductor Energy, use E = ½LI². Inductor Energy uses Inductance, Current to report Stored magnetic energy.

With the loaded values, stored magnetic energy evaluates to 1.60 J. Test inductance separately and preserve the baseline stored magnetic energy. If the next question concerns stored energy, open Capacitor Energy Calculator.

Inputs for Inductor Energy

Inductance and Current belong to Inductor Energy. Keep source units with inductance.

The Inductor Energy defaults demonstrate arithmetic only. Replace inductance with case-specific data. Compare this result with Relay Coil Current Calculator when coil current is also needed.

Inductance

Example entry: 0.05 H.

Current

Example entry: 8 A.

Reading the Inductor Energy result

This output represents Inductor Energy.

Before selecting equipment for Inductor Energy, compare stored magnetic energy with available ratings and operating limits.

Measurement and units

Use component tolerances, voltage ratings, current limits, frequency behavior, and thermal data from the selected parts. Check prefixes on inductance.

Keep the inductance unit and measurement point consistent across Inductor Energy cases.

Limits of this calculation

Core saturation limits usable energy. Use BJT Bias Calculator as the follow-up for base current.

Only the listed Inductor Energy inputs contribute to stored magnetic energy. Unentered effects remain outside Inductor Energy.

A useful Inductor Energy comparison

Record stored magnetic energy before testing a different inductance value.

Document the alternate inductance source.
