One example of a magnet is a refrigerator magnet. These are also called permanent magnets because they always retain a certain degree of their magnetism. There some other general categories for magnets, such as temporary magnets and electromagnets.Know More
Temporary magnets are objects that will act like permanent magnets when they are in a strong magnetic field. Many household objects are temporary magnets, such as paperclips, staples and other related objects.
Electromagnets are magnets that use electrical power to create very powerful magnetic fields. Electromagnetism actually is the technology that allows computers and televisions to work, according to How Magnets Work, a reference site on magnet science topics. Electromagnets work by having a metal core, usually iron, surrounded by a coil of wire. The wire carries a current, which creates the magnetic field. When the current is turned off, however, the apparatus is demagnetized.Learn more about Magnetism
The three primary metal elements that are attracted to magnets are iron, nickel and cobalt. These are also the metals used to create most magnets, although some more powerful magnets use rare-earth elements, such as gadolinium or neodymium.Full Answer >
The north and south poles, often called the negative and positive sides, of a magnet are determined by using the directional properties of magnets. The north pole of the magnet is attracted to Earth's geographical north pole, and the south pole is attracted to Earth's geographical south pole.Full Answer >
A nail that is used in an electricity experiment with wire coiled around it is an example of a temporary magnet. When the electrical current is on, it acts as a magnet, but when it's off, it is no longer magnetic.Full Answer >
A magnet will not stick to titanium. Using a magnet is a common method of determining if a metal that's being sold as titanium is actually titanium.Full Answer >
