Transducer abdominal belts are sometimes used in hospitals to monitor the breathing of patients. One particular model consists of a 200-turn coil of wire wound around a patient's chest. When the patient inhales, the area bounded by the coil increases by 45.0 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 it takes the patient 1.72 s to inhale, a) What is the magnitude of the average emf induced in the coil (in µV) during this time interval? B) Viewed from the top of the patient: What is the sense of induced current?
