9. As shown in figure, a circular loop of wire has a radius R. A magnetic field is directed into the page; its magnitude is given by B(r,t)-Ar²t2, where r is the distance to the center of the loop (origin), and A is a constant. At time t, what is the magnitude of the emf induced in the loop? [10% ] xx ** R xxxx xx B R
