Classical Physics


Magnetism, Interpreted as a Multi-Particle Effect

Authors: Steffen Kühn

In classical electrodynamics, point charges have always an electric as well as a magnetic field. This is a consequence of the Liénard–Wiechert potential, which is the solution of Maxwell's equations for a point charge. This article shows however that it easier to explain the magnetic force of currents and current loops without an explicit magnetic field for every point charge and that it is more probable that magnetic effects arise from the superposition of the single electric fields. The article shows furthermore that both concepts lead to the same results for an infinitely long straight wire and for an infinitely small current loop. The standard way, however, needs strong additional postulates, like a difficult ad-hoc B-field for a point charge and the Lorentz force law. These apriori assumptions are not necessary for the second alternative. The article demonstrates as well that for point charges both concepts are not identically.
