Magnetic Dipole Moment

  • (noun): (physics) a current loop gives rise to a magnetic field characteristic of a magnetic dipole.
    Example: "An orbiting electron in an atom will have a magnetic dipole moment"

    “In Goya’s greatest scenes we seem to see
    the people of the world
    exactly at the moment when
    they first attained the title of
    ‘suffering humanity’”
    —Lawrence Ferlinghetti (b. 1919)

    “We are in great haste to construct a magnetic telegraph from Maine to Texas; but Maine and Texas, it may be, have nothing important to communicate.”
