  2. Magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Magnetic_moment

    m 2 ⋅ A. Dimension. L2I. In electromagnetism, the magnetic moment or magnetic dipole moment is the combination of strength and orientation of a magnet or other object or system that exerts a magnetic field. The magnetic dipole moment of an object determines the magnitude of torque the object experiences in a given magnetic field.

  3. Magnetochemistry - Wikipedia

    en.wikipedia.org/wiki/Magnetochemistry

    Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic.

  4. Electron magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Electron_magnetic_moment

    Electron magnetic moment. In atomic physics, the electron magnetic moment, or more specifically the electron magnetic dipole moment, is the magnetic moment of an electron resulting from its intrinsic properties of spin and electric charge. The value of the electron magnetic moment (symbol μe) is −9.284 764 6917(29) × 10−24 J⋅T−1. [1]

  5. Bohr magneton - Wikipedia

    en.wikipedia.org/wiki/Bohr_magneton

    eħ / me⁠. In atomic physics, the Bohr magneton (symbol μB) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by its orbital or spin angular momentum. [4][5] In SI units, the Bohr magneton is defined as and in the Gaussian CGS units as where. e is the elementary charge, ħ is the reduced ...

  6. Magnetic quantum number - Wikipedia

    en.wikipedia.org/wiki/Magnetic_quantum_number

    Magnetic quantum number. In atomic physics, a magnetic quantum number is a quantum number used to distinguish quantum states of an electron or other particle according to its angular momentum along a given axis in space. The orbital magnetic quantum number (ml or m[a]) distinguishes the orbitals available within a given subshell of an atom.

  7. Magnetization - Wikipedia

    en.wikipedia.org/wiki/Magnetization

    The magnetization field or M-field can be defined according to the following equation: =. Where is the elementary magnetic moment and is the volume element; in other words, the M-field is the distribution of magnetic moments in the region or manifold concerned.

  8. Magnetic susceptibility - Wikipedia

    en.wikipedia.org/wiki/Magnetic_susceptibility

    Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. A related term is magnetizability, the proportion between magnetic moment and magnetic flux density. [3] A closely related parameter is the permeability, which expresses the total ...

  9. Magnet - Wikipedia

    en.wikipedia.org/wiki/Magnet

    A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...
