Question

v Part A We are looking down on an elastic conducting loop with resistance R 162, immersed in a magnetic field. The field's magnitude is uniform spatially, but varies with time 2.2 s according to B(t)-at, where :0.68 T/s . The area A of the loop also increases at a constant rate, according to A(t)-Ag + ßt, where Ao :059 m 2 and :079 m2/s Find the magnitude and direction (clockwise or counterclockwise, when viewed from above the page) of the induced curent within the loop at time t - 22 s if the magnetic field is parallel to the plane of the loop to the right Expresss your answer using two significant figures. I-1.728 Submit X incorrect; Try Again; 5 attempts remaining Part B The resulting current is in the counterclockwise direction The resulting current is in the clockwise direction. O The direction cannot be determined, because the current is zero. Submit

Explanation / Answer

part A)

induced emf = change in magnetic flux/time taken

= 0 (since the magnetic flux through the loop is zero as magnetic field is parallel to the plane of the loop)

so, induced current, I = 0

part B) The direction can not be determined, because the current is zero.
