Which description matches a fridge magnet's composition?

• A. A single large bar magnet
• B. Several magnets arranged end-to-end to form a loop
• C. Tiny horseshoe magnets lined up in alternating north and south poles
• D. A magnet that loses magnetism when heated

Answer: (C)

Fridge magnets are usually built from many small magnets embedded in a flexible backing rather than a single solid piece. When tiny magnets are lined up with alternating north and south poles along the surface, the magnetic field reaches the metal of the fridge more evenly and with a strong grip, while letting the magnet bend to fit the door. This setup matches typical fridge magnets' construction: lots of small magnets arranged so the attraction works across the visible face. A single large bar magnet wouldn't distribute the pull as evenly; a loop of magnets end-to-end is unusual for a flat magnet; and a statement about losing magnetism when heated describes a material property, not how the magnet is put together.
