1. The density is used for calculation of cross sectional area of test piece.
2. Iron loss W15/50 means the iron loss when the frequency is 50HZ and the maximum magnetic flux density is 1.5T。(1T＝1Wb/m²)
3. Magnetic flux density B₅₀ mean the magnetic flux density at a magnetic field strength of 5000 A/m.
