In magnet exploration, which activity would pose a safety risk due to potential ingestion by children?

• A. using a set of very small magnetic beads to create two- and three-dimensional shapes
• B. using a horseshoe magnet to find items the magnet can lift
• C. using a pair of handheld bar magnets to explore magnetic attraction and repulsion
• D. using jumbo alphabet-letter magnets to attach to a magnetic board

Answer: (A)

Tiny magnetic components pose an ingestion hazard for young children. When swallowed, small magnets can attract across loops of the digestive tract, causing pressure, tearing, blockages, infection, and potentially life-threatening injuries that may require surgery. This risk is highest with very small magnetic beads used to form shapes, because they’re easy to put in the mouth and hard for a child to control once play begins. In contrast, activities that use larger magnets or items that aren’t small enough to swallow—such as magnets used to lift objects, handheld magnets to explore attraction and repulsion, or jumbo alphabet magnets on a board—present a much lower ingestion risk, though supervision and safe handling are still important. The key idea is avoiding tiny, swallowable magnetic pieces during play with young children.
