61 "... electromagnetic force" "In physics, the Lorentz force is the force on a point charge due to electromagnetic fields. Lorentz introduced this force in 1892. However, the discovery of the Lorentz force was before Lorentz's time. In particular, it can be seen at equation (77) in Maxwell's 1861 paper On Physical Lines of Force. Later, Maxwell listed it as equation "D" of his 1864 paper, A Dynamical Theory of the Electromagnetic Field, as one of the eight original Maxwell's equations. In this paper the equation was written as follows where
