• pulling a (N) pole out of the solenoid

• pushing a (S) pole into the solenoid

• pulling the solenoid away from a (N) pole

• pulling the solenoid away from a (S) pole

• the current in the loop flows first in a clockwise , then in a counterclockwise

• the current in the loop flows first in a counterclockwise, then in a clockwise direction

• the current in the loop always flows in a clockwise direction

• the current in the loop always flows in a counterclockwise direction

• no current flows in the loop because both ends of the magnet move through the loop

• the induced emf is 4 times as much

• the induced emf is twice times as much

• the induced emf half as much

• there is no change in the induced emf
