The presently constituted laws of physics do not allow us to explain the forces that exist when current-carrying conductors are in a magnetic field, if these conductors are within a magnetically permeable structure. This is of significance if for no other reason than because most motors wound on an iron core fit into this case, and the mechanism by which they work is not now truly explainable. This article will explain the problem, discuss an experiment that was conducted to isolate the forces that exist on the magnetic structure and the conductor, and finally suggest a revision in the expression for the electromagnetic force law1 which also accounts for situations where the current-carrying conductors are within a magnetically permeable structure.
