In the above figures, what are directions of induced current? a) clockwise, b) clockwise a) counter clockwise, b) clockwise a) counter clockwise, b) counter clockwise a) clockwise, b) counter clockwise An emf may be induced in a coil by if the rectangular coil rotate in am uniform magnetic field moving one end of a bar magnet through the coil if the coil remains at rest in a uniform static magnetic field moving the coil toward one end of the bar magnet if the coil remains at rest in a nonuniform static magnetic field Question 4 0 / 1 pts Wire 1 of

in length forms a one-turn loop, and a bar magnet is dropped through. Wire 2 of
100 cm
in length forms a two-turn loop, and the same magnet is dropped through. Compare the magnitude of the induced voltages in these two cases.
