Giving out 100 points is like giving out 100 dollars. Because i worked so hard for this, so take it like you mean it, this is free. But remember how hard i work for thoses 100 points, it can also affect me if anyone reports, because now that is a waste, and again i worked so hard for these 100 points.

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?
