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?

B. A large current forms, drops to zero, then a smaller current forms in the opposite direction

Explanation:

The results of Lionel observation about electromagnetic induction is as follows:

In the first step, a large current will form because of the fast or quick movement of the magnet into the right end of a solenoid that generates a  induces emf.

In the second step, the magnet was in rest position for 3 s so the current drops to zero because according to Faraday's law, no voltage will be generated if the magnet held stationary and no voltage means no current.

In the third step, smaller current forms in the opposite direction as the magnet is slowly moving away from the solenoid generating a smaller voltage.

Hence, the correct answer is "B."
