To monitor the breathing of a hospital pa- tient, a thin belt is girded around the patient's chest. The belt is a 102 turn coil. When the patient inhales, the area encircled by the coil increases by 38.6 cm. Find the average induced emf in the coil during this time. Assume the magnitude of the Earth's magnetic field is 41 T and makes an angle 27.5° with a line drawn perpendicu- larly to the plane of the coil. A patient takes 1.31 s to inhale. Answer in units of uV. 2
