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.Know More
All materials have tiny internal magnetic fields called domains, but in these three ferromagnetic metals, the internal magnetic domains are uniformly aligned to give them a magnetic field. In all other elements, the internal magnets are either randomly oriented or cancel each other out, which is why these other metals don't have a magnetic field.
The ferromagnetic metals are often combined with other metals to create alloys, which also have magnetic properties. For instance, steel is an alloy made from iron that is magnetic, although not to the same degree as pure iron.
Most magnets are made from one of these three metals, which is then heated until the metal reaches its specific Curie temperature. The Curie temperature is the specific temperature at which a ferromagnetic metal takes on the properties of a magnet. If the material is only heated to the exact Curie temperature, the magnetic effects are only temporary. The magnetic properties can be made more permanent by heating the metal up beyond this temperature.Learn more about Magnetism
Metals that are attracted to magnets include iron, nickel and cobalt. The majority of metals are not attracted to magnets, including copper, silver, gold, magnesium, platinum and aluminum. However, the metals that are not attracted to magnets may magnetize slightly when placed in a magnetic field.Full Answer >
The magnetic field of a permanent magnetic material destabilizes on its own over a long period of time, generally on the order of hundreds of years. Magnets, however, weaken more quickly when they are exposed to physical shocks, other magnetic or electrical fields, and high temperatures.Full Answer >
A magnet is made of any of a group of metals called ferromagnetic metals. Ferromagnetic metals contain many small magnetic fields called domains. In their natural state, the magnetic fields of these domains point in different directions. To create a magnet, the magnetic fields must align in the same direction.Full Answer >
Magnets have a north and south pole, and bringing two like poles together repels magnets while unlike poles attract each other. The distance in which two magnets begin to repel or attract each other is determined by the strength of the magnetic field.Full Answer >
