  2. Magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Magnetic_moment

    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. When the same magnetic field is applied ...

  4. Magnetic dipole–dipole interaction - Wikipedia

    en.wikipedia.org/wiki/Magnetic_dipoledipole...

    Roughly speaking, the magnetic field of a dipole goes as the inverse cube of the distance, and the force of its magnetic field on another dipole goes as the first derivative of the magnetic field. It follows that the dipole-dipole interaction goes as the inverse fourth power of the distance. Suppose m 1 and m 2 are two magnetic dipole moments ...

  5. 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 ...

  7. Nuclear magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_moment

    The nuclear magnetic moment is the magnetic moment of an atomic nucleus and arises from the spin of the protons and neutrons. It is mainly a magnetic dipole moment; the quadrupole moment does cause some small shifts in the hyperfine structure as well. All nuclei that have nonzero spin also have a nonzero magnetic moment and vice versa, although ...

  8. Geomagnetic pole - Wikipedia

    en.wikipedia.org/wiki/Geomagnetic_pole

    Like the North Magnetic Pole, the North Geomagnetic Pole attracts the north pole of a bar magnet and so is in a physical sense actually a magnetic south pole. It is the center of the 'open' magnetic field lines which connect to the interplanetary magnetic field and provide a direct route for the solar wind to reach the ionosphere.

  9. Magnetization - Wikipedia

    en.wikipedia.org/wiki/Magnetization

    In classical electromagnetism, magnetization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material. Accordingly, physicists and engineers usually define magnetization as the quantity of magnetic moment per unit volume. [1] It is represented by a pseudovector M.
