The magnetic core shown is made from laminations of M-5 grain-oriented electrical steel. The winding is excited with a 60-Hz voltage to produce a flux density in the steel of ẞ=1.5 sin wt T, where w=2 π 60≈ 377 rad/sec. The steel occupies 0.94 of the core cross-sectional area. The mass-density of steel is 7.65 g/cm³. Find the (a) the applied voltage, (b) the peak current, (c) the rms exciting current, and the core loss.
