An iron rod with diameter of 1.5-centimeter was formed into an almost perfect circular ring (including the air gap at the joint) having an average centerline radius of 10.0-centimeter. The air gap is 0.25 centimeter in length. A coil of 200 turns was wounded on the ring and a current of 5.0-amperes DC was made to flow using external DC source. Considering magnetic flux fringes on the air gap , the effective cross sectional area of the air gap increased by 5% compared to that of the rod. Relative Magnetic Permeability of Iron = 5500. Consider the average or centerline circumference of the ring as the total magnetic path (rod+airgap). 1. What is the total Reluctance of the ring ( rod + air gap ) (A-turns/Wb) ? 2.What is the magnetic flux generated in the ring? 3. What is the magnetic flux density in the air gap
