Voltage in smaller loop = rate of change of flux = Area*dB/dt
= pi*0.04^2*[5.5/1.6e-4]
= 172.8 V
current = V/R= V/[rho*L/A] = 172.8/[2.44e-8*2pi*0.04/0.003]
= 84534756 A
clockwise according to Lenz law.

For this problem, you need to determine the magnetic field at the center of the large loop. The formula for that is B- Hol where R is the radius of the loop 2R A small circular loop of wire of radius 5.0 cm and resistance R = 1.7 x 10-3 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop which initially carries a clockwise current I- 6.4 A, is...
