Question
(a) Describe the method for determination of B-H curve of a magnetic material using step by step method.
(b) In a test on a specimen of total weight 13 kg, the measured values of iron loss at a given value of peak flux density, were 17.2 W at 40 Hz and 23.9W at 60 Hz. Estimate the values of hysteresis and eddy current losses in W/kg at 50 Hz for the same value of peak flux density.
