A long solenoid of radius R carries a time t dependent current I t L 1 t A ring of radius 2R is placed coaxially near its middle During the time interval 0 t 1 the induced current 1 and the induced EMF V in the ring change as 1 At t 0 5 direction of I reverses and V is zero 2 Direction of I remains unchanged and VR is zero at t 0 25 3 Direction of Ip remains unchanged and VR is maximum at t 0 5 4 At t 0 25 direction of Ip reverses and VR
