1. Refrigerator Doors: Most refrigerators use magnets to keep the door securely closed. The door itself has magnets embedded in it, and these magnets are attracted to a metal strip (usually steel) on the refrigerator frame.

2. Magnetic Bottle Openers: These handy tools use a strong magnet to easily remove bottle caps. The magnet is encased in a handle, and when you place it over the bottle cap, the magnet pulls the cap off.
