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

Suppose that a rectangular toroid has 2000 windings and a self-inductance of 0.040 H. If h = 0.10 m, what is the current flowing through a rectangular toroid when the energy in its magnetic field is 2.0 × 10-6 J?
To monitor the breathing of a hospital patient, a thin belt is girded around the patients chest as in Figure P20.21. The belt is a 200-turn coil. When the patient inhales, the area encircled by the coil increases by 39.0 cm2. The magnitude of Earths magnetic field is 50.0 T and makes an angle of 28.0 with the plane of the coil. Assuming a patient takes 1.80 s to inhale, find the magnitude of the average induced emf in the coil during that time. Figure P20.21

You need to redesign an existing inductor so that it will store four times as much energy in the magnetic field with the same applied current as your existing inductor. You can accomplish this by which of the following options. Select all that apply. Question 7 options: Increase the number of windings by 4. Increase the number of windings by 2. Decrease the area of the inductor by 2. Increase the length of the inductor by 4. Increase the area of the inductor by 4. None of the other responses are correct.
A 3.7 mH inductor is initially connected to a 4.6 V battery at t = 0 through a 3.0 Ω resistor.
