Description

It is presented the origins of Weber?s electrodynamics (1846). Amp?re?s force between current elements is discussed and compared with Grassmann-Biot-Savart?s law. Lorentz?s force is compared with Weber?s force. It is discussed a different prediction of these two formulations, namely, the force on an accelerated test charge generated by a uniformly charged spherical shell at rest around the test charge. According to Weber?s electrodynamics the test charge should behave as having an effective inertial mass depending upon the charge of the surrounding spherical shell. Nothing of this should happen according to Lorentz?s force. Orders of magnitude for this predicted effect are presented. Modern experiments and theoretical developments related to Weber?s electrodynamics are also discussed.
