In electromagnetism, the magnetic moment is the magnetic strength and orientation of a magnet or other object that produces a magnetic field. Examples of objects that have magnetic moments include loops of electric current (such as electromagnets), permanent magnets, elementary particles (such as … Meer weergeven Definition The magnetic moment can be defined as a vector relating the aligning torque on the object from an externally applied magnetic field to the field vector itself. The relationship … Meer weergeven Torque on a moment The torque τ on an object having a magnetic dipole moment m in a uniform magnetic field B is: $${\displaystyle {\boldsymbol {\tau }}=\mathbf {m} \times \mathbf {B} }$$. This is valid … Meer weergeven The magnetic field of any magnet can be modeled by a series of terms for which each term is more complicated (having finer angular detail) than the one before it. The first three terms of that series are called the monopole (represented by an isolated … Meer weergeven The magnetic moment is a quantity that describes the magnetic strength of an entire object. Sometimes, though, it is useful or … Meer weergeven The preferred classical explanation of a magnetic moment has changed over time. Before the 1930s, textbooks explained the moment … Meer weergeven Magnetic field of a magnetic moment Any system possessing a net magnetic dipole moment m will produce a dipolar magnetic field (described below) in the space … Meer weergeven The magnetic moment has a close connection with angular momentum called the gyromagnetic effect. This effect is expressed on a macroscopic scale in the Einstein–de Haas effect Meer weergeven http://iris.elf.stuba.sk/JEEEC/data/pdf/7s_115-14.pdf WebMany permanent magnet materials are manufactured so that magnetic properties are enhanced along a preferred axis. This is realized if the crystal lattice structure of the material itself has preferred directions for alignment of the magnetic moments, and is referred to as magnetocrystalline anisotropy. university of sunderland companies house
