Magnetic State - an overview ScienceDirect Topics

WebThe magnetic state of a substance is described by a quantity called the magnetization vector, M. The magnitude of the magnetization vector is equal to the magnetic moment per unit volume of the substance. The total magnetic field in a substance depends on both the applied (external) field and the magnetization of the substance. 3Types of magnetism Toggle Types of magnetism subsection 3.1Diamagnetism 3.2Paramagnetism 3.3Ferromagnetism 3.3.1Magnetic domains 3.4Antiferromagnetism 3.5Ferrimagnetism 3.6Superparamagnetism 3.7Other types of magnetism 4Electromagnet 5Magnetism, electricity, and … See more Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of … See more Magnetism was first discovered in the ancient world when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. The word magnet comes from the Greek term μαγνῆτις λίθος magnētis lithos, "the Magnesian stone, … See more An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when … See more As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as See more Magnetism, at its root, arises from three sources: 1. Electric current 2. Spin magnetic moments of elementary particles See more Diamagnetism Diamagnetism appears in all materials and is the tendency of a material to oppose an applied magnetic field, and therefore, to be repelled by a magnetic field.
