One of these will precess about an applied field with the Larmor frequency, and the torque on a current loop is given by the cross product of this quantity with the magnetic field.
The radiation emitted during orbital-electron capture is a consequence of the disappearance of the charge and of this quantity. Taking the cross product of this quantity with the position vector and dividing it by the absolute value of the position vector cubed yields a quantity proportional to the dipole vector potential. The quantum of this quantity is given by the fundamental charge times h-bar over the quantity two times electron mass times the speed of light. As an adiabatic invariant, the conservation of this quantity results in the creation of a namesake bottle used in plasma confinement. One of these will precess about an applied field with the Larmor frequency, and the torque on a current loop is given by the cross product of this quantity with the magnetic field. Quantized in units of the Bohr magneton, for 10 points, identify this vector quantity which gives the magnitude and direction of an object's magnetic field.
