Definition of magnetic moment in US English:

magnetic moment


  • The property of a magnet that interacts with an applied field to give a mechanical moment.

    • ‘At very low temperature this metal develops magnetic order, whereby the magnetic moments of its electrons align with one other.’
    • ‘Scientists have recently achieved breakthrough quantum mechanical simulations of magnetic moments at high temperatures.’
    • ‘Recent experiments support the idea that crystal defects may be responsible for the quantum tunnelling of magnetic moments in molecular magnets at low temperatures.’
    • ‘Electron spins are easier to detect than nuclear spins because an electron's magnetic moment is 658 times stronger than a proton's.’
    • ‘The holmium atoms in this salt all behave like tiny magnets and, in the absence of a magnetic field, their magnetic moments point in random directions.’
