Magnetism is a force that is created when objects are attracted or repelled by one another. A magnetic field is the area around a magnet. The larger the magnet and the closer an object is to the magnet, the greater the force of the magnetic field. more »

Magnets are objects that produce a magnetic field of varying degrees of strength, attracting or repelling metal objects and other magnets. Over time, a magnet may begin to lose its magnetic strength. Learn how to charge a magnet to restore its magnetic field. more »

Rare-earth magnets have much larger magnetic fields than other magnetic materials. These are the strongest permanent magnets available. more »

When the magnetic dipoles of a metallic object are aligned into a direction, magnetism occurs. To demagnetize a magnet, you must randomize, or cause disorder, in the magnetic dipoles. There are several ways to do so. more »

A magnet is any object with a magnetic field. In order for a magnet to attract an object, the object needs to be ferromagnetic. However, magnets can attract each other when the poles are opposite. more »

Magnets have both a north and south pole; whichever pole of one magnet faces a pole of the other determines whether the magnets attract or not. Iron is a common material used as a magnet. more »

Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron first enters the magnetic field of a magnet. the polarization of the iron's atoms is random. As it is exposed to the magnetic field, the atoms of the iron begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects. This is why a piece of iron that is exposed to a strong magnet becomes magnetic itself for a period of time afterward. more »

The basic idea behind making a magnet is simply magnetically charging a metal object, therefore turning it in to a magnet. Making a magnet in this manner is more of a science experiment, or something you do when you are in a jam and need a magnet. Here are two examples of how to make magnets. more »

A magnet is any material or object that produces a magnetic field. The magnetic field is invisible but attracts ferrous metals including iron and steel. In addition, any object with a magnetic field will either attract or repel other magnets. Not all magnets are permanently magnetized. Hard metals and commercial magnets are permanent magnets that have often been superheated to create a more lasting magnetic field, while other metal objects (such as non-super-heated iron) can be temporarily magnetized but then lose their magnetic field some time after they leave the proximity of another magnet. more »
