Title: Proof Of The Identity Between Ampère And Grassmann's Forces
Author: Bueno M.
Assis A.K.T.
Abstract: We consider a poloidal current flowing over the surface of a conducting cylinder of length l and radius a. We calculate exactly the force on a surface current element belonging to this cylinder due to the remainder of the circuit with Ampère and Grassmann's expressions. We conclude that the formulae agree with one another for any value of l/a. We then generalize this result for any current element belonging to a closed surface or volumetric currents of arbitrary forms.
