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?

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

not too sure thinking all accelerations are pointed down

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
