Gyromagnetic ratio

<p>
In <a href="/facts/Physics/a7aH2y08">physics</a>, the gyromagnetic ratio (also sometimes known as the magnetogyric ratio in other disciplines) of a particle or system is the <a href="/facts/Ratio/mFmhQt7T">ratio</a> of its <a href="/facts/Magnetic_moment/VpAQKJtr">magnetic moment</a> to its <a href="/facts/Angular_momentum/7TuSVFxq">angular momentum</a>, and it is often denoted by the symbol <a href="/facts/Gamma/RkmPeRj3">γ</a>, gamma. Its <a href="/facts/SI/S7YLglNz">SI</a> unit is the reciprocal second per <a href="/facts/Tesla_(unit)/K6I5Stn9">tesla</a> (s−1⋅T−1) or, equivalently, the <a href="/facts/Coulomb/WNV9ueGr">coulomb</a> per <a href="/facts/Kilogram/lU2zbPk8">kilogram</a> (C⋅kg−1).
</p><p>The <a href="/facts/G-factor_(physics)/kmDsyF5g">g-factor</a> of a particle is a related <a href="/facts/Dimensionless/TINrpQIq">dimensionless</a> value of the system, derived as the ratio of its gyromagnetic ratio to that which would be classically expected from a rigid body of which the mass and charge are distributed identically, and for which total mass and charge are the same as that of the system.
