Explanation / Answer

part B)

for the current in the loop

di/dt = (-20 - 20)/1 = - 40 A/s

Now , for the induced current

induced current * R = rate of change of magnetic flux

I * 0.17 = 4pi *10^-7 * 100 * (40)/.15 * pi * (0.02/2)^2

solving for I

I = 6.19 *10^-5 A

the current induced is 6.19 *10^-5 A
