To monitor the breathing of a hospital patient, a thin belt is girded around the patient?s chest as in figure. 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 the Earth?s 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.
