Question

O-1 points SerCP11 202P 021 To monitor the breathing of a hospital patient, a thin belt is girded around the patient's chest as in the figure below. The beit is a 160-turn coll. When the patent inhales, the area My Noes Ask Your Teacher O encircled by the coll increases by 37.0 cm. The magnitude of Earth's magnetic fleld is 50.0 uT and makes an angle of 27.5 with the plane of the col. Assuming a patient takes 2.00s to Inhale, find the magnitude of the average induced emf in the coll during that time. Coil Read it Need Help?

Answer 1

Here,

Magnitude of Earth's magnetic field is,

B=50*10^-6 T

Then,

so stfon Неsме, Number of turns is N 160 turns The magnitude ob £arths magne tic Field is 3 = 50UT = SOxIOT Pca is', A = 31Cm2 = 37x 10 m2 The anale betmeen magnetic Field and plane is The tme .taken fosr jpatient to in hale is; At oos Then, 0= go-O =30-?7-5 Then, Magnitude of induced Emp in the coil is jadel Nouw, N BALO we put all the values in above equation is (16)x(Sox10)x(a7X |o" )cos62 = 6.76 x1o 6 V ?.O0S 6 76 uv haser)
