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.

You wish to construct a solenoid with a diameter of 2.00 cm that will produce a magnetic field of 3.40 x 10-2T at its center when a current of 12.0 A is passing through the coils. You want the resistance of the coil wire to be 5.80 N. The resistivity of the wire used is 1.70 x 10-8 N •m (at 20.0°C), and you are using a wire that has a cross sectional area of 3.14 × 10-8 m2. (Note that this solenoid may not necessarily be so tightly wound that the adjacent loops of wire will touch each other. Nonetheless, you may assume that it behaves like an ideal solenoid.) Determine the following. (a) number of turns needed on the solenoid turns (b) length of the solenoid
