Respiration monitor belts are sometimes used in hospitals to monitor the breathing of patients. One particular model consists of a 200-turn coil of wire that wraps around a patient's chest. When the patient inhales, the area bounded by the coil increases by 38.0 cm2. The magnitude of the Earth's magnetic field is 50.0 µT and makes an angle of 28.0° with the plane of the coil. If the patient takes 1.75 s to inhale, what is the magnitude of the average induced emf in the coil (in µV) during this time interval? 19.174
