QUES.1 Two air-cored coils are disposed relatively to each other so that 75% of the flux in one coil links all the turns of the other coil. Each coil has a cross-sectional mean diameter of 2cm and a length of 50 cm. If there are 2000 turns of wire on one coil, calculate the number of turns required on the other coil to give a mutual inductance of 20 mH.
