Question

Before beginning an experiment, Mrs. Wilson warns her science class not to drop the bar magnets on the floor.

What is the most likely reason for Mrs. Wilson’s warning?

The magnet might lose its magnetism.
The magnet might make a startling noise.
The magnet might become stuck to the floor.
The magnet might cause the floor to become magnetic.

Answer 1

The magnet might lose its magnetism.

Reason: strong impacts (dropping or striking) can jostle the magnetic domains or damage a magnet so it becomes weaker or demagnetized.
