magnetism. Magnetism is the force exerted by magnet s when they attract or repel each other. Magnetism is caused by the motion of electric charge s. Every substance is made up of tiny units called atoms. Each atom has electron s, particle s that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom.

Magnetism is a class of physical attributes that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.

More about magnetism. Magnetic Field Lines Michael Faraday, credited with fundamental discoveries on electricity and magnetism (an electric unit is named "Farad" in his honor), also proposed a widely used method for visualizing magnetic fields. Imagine a compass needle freely suspended in three dimensions, near a magnet or an electrical current.

Magnetism may be classified according to its cause and behavior. The main types of magnetism are: Diamagnetism: All materials display diamagnetism, which is the tendency to be repelled by a magnetic field. However, other types of magnetism can be stronger than diamagnetism, so it is only observed in materials that contain no unpaired electrons.

De Magnete was the text in which Gilbert revealed the results of his research on magnetism and attempted to explain the nature of magnets and the five motions associated with magnetic phenomena. The work met with great acclaim and was republished in 1628 and 1633. William Gilbert (1544?1603) England. Find something.

Magnetism and electricity: the theory of electromagnetism. Electromagnets show that you can make magnetism using electricity. In fact, as European scientists discovered in the 19th century, electricity always makes magnetism when it moves about or changes. Every time an electric current flows in a wire, it generates a magnetic field all around it.

Magnets seem to act something like positive and negative electric charges. Electricity and magnetism are very closely related. If the words north and south remind you of anything, the earth is in fact a giant magnet. A compass is a tiny magnet balanced on a point so it can turn freely. The magnet is attracted by the earth?s magnetic north ...

Background Magnetism is a property of atoms that produces a field which causes a force that attracts or repels other objects. From Live Science, ?All materials experience magnetism, some more strongly than others. Permanent magnets, made from materials such as iron, experience the strongest effects, known as ferromagnetism. With rare exception, this is the only form of+ Read More
