1. An iron ring of mean length 50 cm and has an air gap of 0.1 mm and a winding of 500 turns. Consider the relative permeability of iron is 250 when a current of 1.5 A flows through the coil. Find the flux density, take He = 4n x 10 H/ m. Assume that the flux density through the iron and air gap is the same.
