Question
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?
