Question

6. A circular ring of magnetic material has a mean length of 1.0m and a cross-sectional
area of 0.001m. A saw cut of 5mm width is made in the ring. Calculate the
magnetizing current required to produce a flux of 1.0mWb in the air-gap if the ring is
wound uniformly with a coil of 200 turns. Take relative permeability of the ring
material = 500 and neglect leakage and fringing.
