Experimental investigation of an unusual induction effect and its
interpretation as a necessary consequence of Weber electrodynamics
Abstract
The magnetic force acts exclusively perpendicular to the direction of
motion of a test charge, whereas the electric force does not depend on
the velocity of the charge. This article provides experimental evidence
that, in addition to these two forces, there is a third electromagnetic
force that (i) is proportional to the velocity of the test charge and
(ii) acts parallel to the direction of motion rather than perpendicular.
This force cannot be explained by the Maxwell equations and the Lorentz
force, since it is mathematically incompatible with this framework.
However, this force is compatible with Weber electrodynamics and
Ampère’s original force law, as this older form of electrodynamics not
only predicts the existence of such a force but also makes it possible
to accurately calculate the strength of this force.
