Question

To monitor the breathing of a hospital patient, a thin belt is girded around the patient's chest. The belt is a 200 turn coil. When the patient inhales, the area encircled by the coil increases by 39 cm squared. The magnitude of Earth's magnetic field is 50.0 micro Tesla and makes an angle of 28 degrees with the plane of the coil. Assuming a patient takes 1.80 seconds to inhale, find the magnitude of the average induced emf in the coil during that time.

E ≈ (200)(50.0e-6)(0.39sin28°)/1.80
E ≈ 0.0010172 V ≈ 1.02 mV
