A ring is in a region of space that contains a uniform magnetic field directed perpendicular to the plane of the ring. The diameter of the ring is 0.33 m. The figure is a graph of the magnetic field as a function of time. What is the magnitude of the electric field along the perimeter of the ring at t=1 s? 15 B (T) -10 O 2 4 6 8 10 t (sec) O 2 V/m 12 V/m 0.3 V/m
