To monitor the breathing of a hospital patient, a thinbelt is girded around the patient's chest. The belt is a233 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 µT andmakes an angle of 28.0° with the plane of the coil. Assuming that a patient takes 1.80 s to inhale, find the average induced emfin the coil during this time.
