A circular coil of 100 loops is positioned between the poles of an electromagnet so that the normal to the plane of the coil makes an angle of 25° with the direction of the field. The coil has a resistance of 3.0 Ω. When the magnet is switched off the magnetic flux density drops at a steady rate, from 0.50 T to zero in 0.10 seconds, causing an induced current of 1.2 A to flow in the coil. Calculate the...
