    Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel. The.

    Magnetism is a force generated in matter by the motion of electrons within its atoms. Magnetism and electricity represent different aspects of the force of electromagnetism, which is one part of the universe ’ s fundamental electroweak force. The region in space that is penetrated by the imaginary lines of magnetic force describes a magnetic.

    Magnetism is the power to attract. It refers to the attraction to iron and other metals in electric currents and magnets, or to the other kind of attraction — where people want to be close to each other.

    Magnetism is an invisible force or field caused by the unique properties of certain materials. In most objects, electrons spin in different, random directions. This causes them to cancel each other out over time. However, magnets are different. In magnets the molecules are uniquely arranged so that their electrons spin in the same direction.

    Magnetism is defined as an attractive and repulsive phenomenon produced by a moving electric charge. The affected region around a moving charge consists of both an electric field and a magnetic field. The most familiar example of magnetism is a bar magnet, which is attracted to a magnetic field and can attract or repel other magnets.

    Oct 25,  · 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.

    Lodestone, or magnetite (Fe 3 O 4), belongs to a class of substances known as ferrites. Ferrites and some other classes of magnetic substances discovered more recently possess many of the properties of ferromagnetic materials, including spontaneous magnetization and remanence.
