单词	magnetic moment
释义	magnetic moment noun : a vector quantity that is a measure of the torque exerted on a magnetic system (such as a bar magnet or dipole) when placed in a magnetic field and that for a magnet is the product of the distance between its poles and the strength of either pole Example Sentences Recent Examples on the Web Part of what sets the axial Higgs boson apart from the Higgs boson is its magnetic moment. Joshua Hawkins, BGR, 9 June 2022 The atoms in a magnetic material like iron or nickel each have something called a magnetic moment, which is basically a tiny individual magnetic field.
