The classical prediction for the electron's value of this quantity is incorrect by a factor of slightly more than two.
One particle's value of this quantity has a sixth-order component for which the first term of the analytic expression contains a factor of 28,259 over 5,184. The interaction of two forms of this quantity generates an energy proportional to two-thirds vacuum permeability; that is the Fermi contact contribution to s-orbital hyperfine structure. This quantity's volume density oscillates in the de Haas-van Alphen effect. The mirror force is proportional to this quantity, and it is the first adiabatic invariant of a plasma. The classical prediction for the electron's value of this quantity is incorrect by a factor of slightly more than two. Subtracting one from half the g-factor gives the anomalous value of this quantity, and dividing this quantity by angular momentum gives the gyromagnetic ratio. For 10 points, name this quantity, defined as the product of the current enclosed by a loop and the vector area of that loop, whose SI unit is the Bohr magneton.
