An iron ring has a tightly wound coil with 1500 turns. The inner and outer radii of the iron core are 10 cm and 12 cm respectively. A radial airgap of length 1 cm is cut in the iron ring. If the current in the coil is 4 A and the relative permeability of the iron is 1200, determine the following: i. The cross-sectional area of the iron core ii. The flux density in the magnetic circuit.
