A coil of wire having inductance and resistance has a conducting ring placed coaxially within it The coil is connected to a battery at time t 0 so that a time dependent current 1 t start flowing through the coil If l2 t is the current induced in the ring and B t is the magnetic field at the axis of coil due to 1 t then as a function of time t 0 the product 12 t B t I 1 6th A increases with time B decreases with time C does not vary with time D passes through a maximum 2000
