They are one of the most commonly used types of magnet, and are strong and is not easy to demagnetize. 3. When two magnets are close, they create pushing or pulling forces on one another. When a permanent magnet picks up a piece of iron or steel, the nail becomes a temporary magnet. This same principle is true for repulsion because magnets with strong poles possess a stronger repulsive force. The object loses its magnetic properties once the electric current ceases to be transferred through the object. The shape of a magnet, however, can tell you a lot more than size. A list of industrial magnet applications would take thousands of words to complete. They power speakers in stereos, earphones, and televisions. Magnetic bearings use the concept of magnetic levitation to support moving parts without physical contact. Electromagnets, which rely on electrical current to generate magnetic fields, are used to powering everything from medical equipment to consumer electronics. There are many practical uses for magnets that we see everyday, but there are so many more ways to use magnets that the maker nerd in all of us will appreciate. But following the guy that answer right before me, i guess the electron build up would be different and take any possition due to some quantum laws, and the difference in air pressure, even just a small amount would tip the magnet.
