Inductor Steinmetz Core Loss Density
Estimate magnetic-core loss density with a fitted Steinmetz power law p=k f^α B^β. Units of k must match the selected frequency, peak flux-density, and desired output units; the model applies only over its fitted waveform/range.

How Inductor Steinmetz Core Loss Density works
Estimate magnetic-core loss density with a fitted Steinmetz power law p=k f^α B^β. Units of k must match the selected frequency, peak flux-density, and desired output units; the model applies only over its fitted waveform/range. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Loss Density
- The resulting loss density returned as a number.
Limitations and assumptions
- Inductor calculations depend on core material, air gap, turns, frequency, waveform, temperature, DC bias, copper resistance, skin and proximity effects, fringing, and saturation definition. Small-signal inductance and nominal current rating may not describe switching operation.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.
