A planar semicircular loop of conducting wire with total resistance r rotates at a constant angular speed about a fixed axis along its straight diameter edge, periodically entering and exiting a region of uniform magnetic field. The magnetic flux \(\Phi_B\) through the loop as a function of time t for one complete revolution of period T is shown in the graph. Which of the following statements correctly describes the magnitude and direction of the induced current in the loop during the intervals \(0 < t < \dfrac{T}{2}\) and \(\dfrac{T}{2} < t < T\)?
