WebThe magnetic field of permanent magnets can be quite complicated, especially near the magnet. The magnetic field of a small straight magnet is proportional to the magnet's strength (called its magnetic dipole moment m). The equations are non-trivial and also depend on the distance from the magnet and the orientation of the magnet. For simple ... Webforth the notion of magnetic equivalent circuit – an approximate but often fairly accurate technique for the analysis of magnetic systems. Using this technique, we will see how to translate a geometrical description of a magnetic device consisting of coils of wire, magnetic conductor such as iron, and permanent magnet material into

Web24 dec. 2024 · In analogy to the orbital angular momentum, the magnitude of the electron magnetic moment is μ s = ( e 2 m e) S. According to the special theory of relativity, this value is low by a factor of 2. Thus, in vector form, the spin magnetic moment is μ → = ( e m e) S →. The z -component of the magnetic moment is (from Equation 8.4.1)
