The Voltaic Origins of Helmholtz`s Physics of Ions
... phenomena to central forces acting on pairs of mass points. Laplacian physics already provided this reduction for gravitational, electrostatic, and magnetostatic phenomena. Helmholtz extended it to electrochemistry. The main facts to be explained were the contact tension of two different metals (now ...

A moving electric charge is surrounded by a magnetic field.
... Where is the motion of electric charges in a common bar magnet? The magnet as a whole may be stationary, but it is composed of atoms whose electrons are in constant motion about atomic nuclei. This moving charge constitutes a tiny current and produces a magnetic field. ...
