Claim 3:
4. The measurement method for the B-H curve of magnetic material according to claim 3, wherein virtual magnetic power {dot over (S)}mc based on the vector model of the magnetic circuit is obtained by the MMF {dot over (F)} and the magnetic flux {dot over (Φ)}, as follows:

{dot over (S)}mc={dot over (Φ)}·{dot over (F)}*={dot over (Φ)}·[Rmc·{dot over (Φ)}*−jωLmc{dot over (Φ)}*]=Rmc∥{dot over (Φ)}∥2−jωLmc∥{dot over (Φ)}∥2.
