The magnetic field between the poles of an electromagnet is 3.30 T. A coil of wire is placed in this region so that the field is parallel to the axis of the coil. The coil has electrical resistance 24.6 Ω and radius 1.80 cm. When the current supply to the electromagnet is shut off, the total charge that flows through the coil is 9.00 mC. How many turns are there in the coil?

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...
