A nonconservative action is properly derived from a nonconservative force. The one and only nonconservative fundamental force is the magnetic force. It is the scalar product of electric charge and the outer vector cross product of the magnetic field and the local infinitesimal velocity of the electric charge.

Since electric charges are fully integrated directional properties of space-time charges the nonconservativeness of magnetic force is intimately related to the infinitesimal local motion (LIM) of space-time charges. LIM serves as the irreducible fundamental third quantization of space-time local motion as both 180° and 360° twist Möbius bands respectively for quarks and leptons.
