Background: A small circular loop of wire of radius 5 cm and resistance 1E-3 Ω is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.) (I) The induced electric field in the wire and the average current pointed in the same direction? True or False? (J) Direction of B inside the small loop as a result of the induced current:______
