A solenoid ring with N = 3 loops is immersed in a uniform time-varying magnetic field (shown in the figure) whose strength is given by B = (1/4) sin(t/2) [T], where t is in seconds. If the radius of the loop is r = 2[m], what is the maximum magnitude of the EMF in the loop? At what time is the magnitude of the EMF at half its max value? X xx X X X x/xxx\x X X X X x\x x x/x
