Title :
Basic sources of electric and magnetic fields newly examined
Author :
Bennett, W. Scoff
Abstract :
The current element and the physical origins of its electric and magnetic fields are simply explained. In the course of the discussion, Coulomb´s law and the Biot-Savart law are extended to include the time-varying point sources that make up a current element.
