Electromagnetic Induction

Question 2 • (OC27) Earth/Space Sci-2001310-S2-Nelson

Lionel explores electromagnetic induction using the procedure shown.1. Move the magnet quickly into the right end of a solenoid.2. Hold the magnet in the solenoid for 3 s.3. Move the solenoid slowly to the left away from the magnet.What should Lionel observe during his investigation?

Answer
A
A large current forms, drops to zero, then remains at zero.
B
A large current forms, drops to zero, then a smaller current forms in the opposite direction.
C
A large current forms, drops to zero, then a smaller current forms in the same direction.
D
A small current forms, drops to zero, then a larger current forms in the same direction.

Explanation

Moving the magnet quickly into the solenoid changes the magnetic flux rapidly, producing a large current. While the magnet is held still, the flux does not change, so the current drops to zero. Moving the solenoid slowly away reverses the change in flux, producing a smaller current in the opposite direction.
