Ampere vs. Grassmann on Experimental Grounds

摘要

The growing interest in a thorough revision of the tenets of classical electrodynamics [1] compels thephysics community to reconsider the dominating magnetic field rationale applied to electrodynamics since thetime of Lorentz. The torque-production mechanism presently attributed to homopolar machines, which isbased on Grassmann's force, has been definitively ruled out by recent crucial experimentation. Conversely,Ampere's force law, restating the Newtonian symmetry requirement for energy conversion, fully explains ho-mopolar torque production [2].
