Draw hysteresis (B-H curve) of a specimen in the form of a transformer and to determine its hysteresis loss
1. The Hysteresis loop of a magnetic material has an area of 5 cm2 with the scales given as 1 cm = 2 AT and 1 cm = 50 mWb. At 50 Hz the total hysteresis loss is
2. Hysteresis loss is given by:
3. Which factor does NOT affect hysteresis loss (Ph)?
4. Which material property influences the shape of the hysteresis loop?
5. A magnetic material with a hysteresis loop area of 2.5 J/m³ is subjected to an alternating magnetic field at a frequency of 60 Hz. If the material has a volume of 0.01 m³, calculate the total hysteresis loss per second.
