5. A magnetic toroid of 500 turns, cross sectional area of 4 cm² and diameter of 10cm is made of aluminum. If the flux density in the copper core is to be 10.6mT and relative permeability ur of coppercore is 20, then calculate: i. The exciting current required to be passed in the winding; ii. The value of self-inductance; and iii. The stored energy.
