Question

Please show all work.Thanks.

A flexible loop has a radius of 13.3 cm and it is in a magnetic field of B = 0.194 T. The loop is grasped at points A and B and stretched until its area is zero. It takes 0.228 s to close the loop. What is the magnetic flux through the loop before it is streched? Submit Answer Tries 0/12 What is the maanetic flux through the loop after it is stretched? Submit Answer Tries 0/12 What is the magnitude of the average induced electromotive force in the loop during the stretching process? Submit Answer Tries 0/12

Explanation / Answer

a) r = 0.133 m, B = 0.194 T, dt = 0.228 s

magnetic fluxbefore = B * A = 0.194 * pi * 0.1332

phibefore = 0.011 T.m2

b) magnetic fluxafter = B * A = 0.194 * 0

phibefore = 0 T.m2

c) E= -dphi / dt = phiafter - phibefore / dt

= (0.011 ) / (0.228)

= 0.047 V
