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. Quanta Magazine, 11 Nov. 2021 However, the magnetic moment of an actual piece of iron would depend on the strength of the magnetic field that induces it. Rhett Allain, Wired, 31 Dec. 2021 The magnetic moment for the carrot is a bit more difficult. Rhett Allain, Wired, 31 Dec. 2021 In 2017, after more than a decade of work, Laporta published his magnum opus — the electron’s magnetic moment to 1,100 digits of precision. Quanta Magazine, 22 Nov. 2021 Fermilab’s new high-precision measurement of the magnetic moment is a remarkable experimental achievement. Sabine Hossenfelder, Scientific American, 7 Apr. 2021 Both measurements of the muon’s wobbliness, or magnetic moment, significantly overshoot the theoretical prediction, as calculated last year by an international consortium of 132 theoretical physicists. Quanta Magazine, 7 Apr. 2021 Years ago, physicists attempted to measure the magnetic moment of the muon to incredible precision, and got a value. Ethan Siegel, Forbes, 27 Apr. 2021 See More
