Formula and methodology
Formula: U = ½LI²; flux linkage = LI.
An ideal inductor stores energy in its magnetic field, with energy proportional to inductance and to the square of current.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Inductance — H; minimum 1.0E-12; maximum 1000000
- Current — A; minimum 0; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Inductance | 0.01 |
| Current | 2 |
The stored energy is 0.020 J and the flux linkage is 0.020 Wb-turn.
Assumptions and limits
- Inductance is constant over the entered current and the current is a steady magnitude.
- The inductor is treated as ideal with no core saturation, resistance, or loss.
- Switching transients, voltage limits, heating, and component selection are not modeled.
