"If the forward motion is in the same direction as the winds circulating around the hurricane, the net wind speed would be the sustained wind speed plus the forward motion; if the forward motion is in the opposite direction from the winds circulating around the hurricane, the net wind speed would be the sustained wind speed minus the forward motion. Assuming idealized sustained wind speeds around the hurricane, determine which of these statements is true."

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
