A 100 uH inductor carrying 2 A stores 200.0000 uJ in its magnetic field.
Doubling the current to 4.00 A would quadruple the stored energy to 800.0000 uJ, because energy scales with the square of the current.
Halving the current to 1.00 A would reduce stored energy to 50.0000 uJ, one-quarter of the original value.
Inductors oppose changes in current: the larger the stored energy, the more aggressively the magnetic field pushes back against any attempt to reduce the current.
Next stepUse the solve-for selector above to reverse-calculate the inductance or current needed for a specific energy target.
