Soft ferromagnetic material: mu_r = 1.0043

  • A relative permeability in the hundreds to low thousands is typical of soft ferromagnetic materials such as iron powder cores or silicon steel used in power transformers.
  • Magnetic susceptibility chi = 4.2677e-3: small positive value, confirming weak paramagnetic response.

Next stepFor core loss and saturation calculations, pair this result with a B-H curve for your specific material grade. Consult manufacturer datasheets for exact mu_r values under your operating conditions.
