More precisely, the term magnetic moment normally refers to a system's magnetic dipole moment, the component of the magnetic moment that can be represented by an equivalent magnetic dipole: a magnetic north and south pole separated by a very small distance. Meer weergeven 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 … Meer weergeven The preferred classical explanation of a magnetic moment has changed over time. Before the 1930s, textbooks explained the moment using hypothetical magnetic point charges. Since then, most have defined it in terms of Ampèrian currents. In magnetic materials, … 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 surrounding the system. While the net magnetic field produced by the system can also … 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 … Meer weergeven The magnetic moment is a quantity that describes the magnetic strength of an entire object.

Spin magnetic moment - Wikipedia
WebThe orbital magnetic dipole moment is a measure of the strength of the magnetic field produced by the orbital angular momentum of an electron. From Force and Torque on a Current Loop, the magnitude of the orbital magnetic dipole moment for a current loop is μ = I A, 8.13 where I is the current and A is the area of the loop. WebMagnetic moments in a material can precess about their equilibrium direction in the presence of a magnetic field. A collection of such precessions can propagate in the material and is usually termed a spin wave.31–35 This terminology is based on the fact that the moments in most magnetic materials originate essentially from electron spins. WebLenz's law is a consequence of conservation of energy applied to electromagnetic induction. It was formulated by Heinrich Lenz in 1833. While Faraday's law tells us the … garfield convention
