Acircular wire loop of radius 15.0 cm carries a current of 2.60 a. it is placed so that thenormal to its plane makes an angle of 41.0◦with a uniform magnetic field of magnitude12.0 t. (a) calculate the magnitude of the magnetic dipole moment of the loop. (b)what is the magnitude of the torque acting on the loop?

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?
