A semicircular loop of radius R is rotated about its straight edge which divides the space into two regions one having a uniform magnetic field B and the other having no field. If initially the plane of loop is perpendicular to B (as shown). And if current flowing from O to A be taken as positive, the correct plot of induced current v/s time for one time period is :
