Explanation

As the Magnus force applies at the CPM, which does not necessarily coincide with the CG, a Magnus moment MM (see figureGo to figure) is associated with that force. The location of the centre of pressure of the Magnus force depends on the flow field and can be located ahead or behind the CG. The Magnus moment turns out to be very important for the dynamic stability of spin-stabilized bullets. For the Magnus moment, the above expression is used in exterior ballistics.
