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 10 5 B(T) -5 -10 0 2 4 6 8 10 t (sec) O 12 V/m O 6 V/m O 0.3 V/m O 2 V/m O 0.01 V/m
