Things to Do With a Super Magnet

Lost Objects

• When you lose something metallic in a narrow crevice or hole, remove it with a super magnet. If your magnet has a loop or hook, you may tie a string to it and lower the magnet into the crevice, if necessary (use some tape to ensure it stays on the hook). If you should lose the super magnet in a crevice, use a piece of metal to retrieve it, rather than another magnet.

Holding Together

• The high strength of such magnets enables them to hold things together quite tenaciously, although not permanently. To do this, simply put anything between a super magnet and a piece of metal. You may use it for thicker objects than most traditional magnets will hold. Avoid directly placing the super magnet on a flat metal surface; it may prove difficult to remove.

Permanent Eraser

• A super magnet permanently damages a computer floppy disk, where other magnets often fail, according to Colorado State University. Although you don't normally want this to happen, it's useful if you really want to delete personal information on a disk beyond recovery (account numbers, passwords). Delete the files first, then apply the super magnet to different parts of the disk.

Audio Speaker

• All headphones, earphones and speakers use magnets. Some high-end audio devices now use super magnets for this purpose, according to RareMetalInvestor.com. It's possible to make your own speaker using a few inexpensive household items, though you need to buy an audio jack or adapter to connect the speaker to some models of radio receivers and stereo systems.

Metal Detector

• If you don't want to spend the money on a metal detector, a super magnet permanently mounted to the end of a pole also helps you find metallic things. Unlike a metal detector, it doesn't need batteries to operate, and it picks up objects for you. After securely attaching the magnet to the pole, poke around in the grass or sand until you find some metal.
