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.

The most likely reason for Mrs. Wilson’s warning is that the magnet might lose its magnetism. Dropping a magnet can cause physical damage to its internal structure, which can disturb the alignment of its magnetic domains and reduce its overall magnetism.
