Question

Question 4: The magnetic core in Fig. 1 is made from laminations of M-5 grain–oriented
electrical steel. The winding is excited with 60-Hz voltage to produce flux density in the steel
of B=1.5sinωt T, where ω=2π60 rad/sec. The steel occupies 0.94 of the core cross-section
area. The mass-density of the steel is 7.65g/cm3
. Find (a) The applied voltage, (b) The peak
current, (c) The rms exciting current, and (d) The core loss.
