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 diameter of the coil.
