I know how to solve the problem with the equation given. However when i substitute the values my calculator keeps giving me a certain answer (which is wrong). Ive tried at least 5 times already.

To monitor the breathing of a hospital patient, a thin belt is girded around the patient's chest as in the figure below. The belt is a 185-turn coil. When the patient inhales, the area encircled by the coil increases by 37.0 cm2. The magnitude of Earth's magnetic field is 50.0 T and makes an angle of 25.5° with the plane of the coil. Assuming a patient takes 1.70 s to inhale, find the magnitude of the average induced emf in the coil during that time.

example on how to solve:

|| = N(B) t = NB(A) cos t = 195(5.00 105 T)[(38.0 cm2)(1 m2/(104 cm2))] cos 64.0° 1.90 s = 8.55 106 V = 8.55 V.

Explanation / Answer

E=N(change in flux)/time

flux = BA cos (angle between B and A)

let initial area be A cm ^2

new area =(A + 37)cm^2

change in flux = NB(in Tesla)(37*10^-4)cos(64.5)=1.47 *10^-5

e=change in flux/time=8.66*10^(-6) V

change in flux =
