Q2. A simple relay has an airgap of length 1.0 mm and effective cross- sectional area 1000 mm². The magnetizing coil consists of 1000 turns of wire carrying a current of 200 mA. Calculate the energy stored in the airgap. The reluctance of the ferromagnetic part of the magnetic circuit may be neglected. (Ans: 4.2 A)
