Question

1) A sample of a magnetic material is known to have a hysteresis energy loss of 300 joules per cycle per cubic meter when the maximum flux density is 1.2 T. Find the hysteresis loss in the magnetic material if the flux density is 0.8 T, the volume of the magnetic material is 40 cm$^3$, and the frequency of operation is 60 Hz. The Steinmetz constant is 1.6. 2) In a given specimen of a magnetic material, the magnetic loss was 21.6 W at a frequency of 25 Hz and a flux density of 0.8 T. When the same specimen was tested at a frequency of 60 Hz, the magnetic loss increased to 58.4 W at the same flux density. What are the hysteresis and eddy-current losses at each frequency? The Steinmetz constant is 1.5.
