Question

The magnetic core in fig. 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 b(t) = 1.5 sin t t, where =2(60) rad/sec. The steel occupies 0.94 of the core cross-sectional area. The mass-density of the steel is 7.65 g/cm3. Find the (i) applied voltage (ii) the peak current (iii) the rms exciting current and (iv)the core loss the magnetic field intensity corresponding to bmax=1.5 t is hmax=36 turns/m
