The switch in the circuit shown in Figure 20.29 is closed, and the light bulb glows steadily. The inductor is a simple air-core solenoid. An iron rod is inserted into the interior of the solenoid, increasing the magnitude of the magnetic field in the solenoid. As the rod is inserted, the brightness of the light bulb (a) increases, (b) decreases, or (c) remains the same.FIGURE 20.29
