You perform experiments using an apparatus that has two insulated wires wrapped around a cardboard tube (Figure P21.3). Determine the direction of the current in the bulb when (a) the switch is closing and the current in coil A is increasing, (b) the switch has just closed and there is a steady current in coil A, and (c) the switch has just opened and the current in coil A is decreasing.

MRI: Magnetic resonance imaging (MRI) uses a very strong magnet to create an image. The maximum strength of the magnetic field is 1.5 T. Because the magnet is switched on and off quickly, it can induce large eddy currents in metal objects. Suppose a patient is wearing a metal ring with a radius of 1.4 cm and a mass of 110 g. Such a ring has a resistance of about 0.016 N. If the magnet in the MRI rises from 0T to its maximum strength of 1.5 Tin 1.94 ms, what is the maximum current that could be induced in the ring?
