Core losses are generated within the magnetic material itself whenever magnetic flux changes over time.
These losses increase with:
- Frequency
- Flux density
- Material characteristics
This calculator helps estimate core losses and evaluate the impact of operating conditions on efficiency and temperature rise.

- Frequency impact
- Flux density impact
SolidMag Engineering Note
Many engineers focus exclusively on copper losses, but core losses often dominate at higher switching frequencies. Both must be considered for an accurate thermal analysis.
