A metal ring 4.50 cm in diameter is placed between the northand south poles of large magnets with the plane of its area perpendicularto the magnetic field. These magnets produce an initial uniform field of1.12 T between them but are gradually pulled apart, causing this fieldto remain uniform but decrease steadily at 0.250 T/s. (a) What is themagnitude of the electric field induced in the ring? (b) In which direction(clockwise or counterclockwise) does the current flow as viewedby someone on the south pole of the magnet?
