A new method for calculating electric and magnetic forces is presented. The method makes it possible to calculate forces directly from scalar and vector potentials rather than from field vectors. Several new force equations are derived. They are grouped in four categories: equations for calculating ...
According to special relativity, electrostatic forces and magnetic forces are actually one and the same thing, dependent on the viewers perspective. We talk about fundamental physics here, and for me, it was very confusing, wheater magnetic is primer over electric or vice versa. But in the end,...
Magnetism - Electric Currents, Forces, Fields: Magnetic fields produced by electric currents can be calculated for any shape of circuit using the law of Biot and Savart, named for the early 19th-century French physicists Jean-Baptiste Biot and Félix Sav

The meaning of ELECTRIC FIELD is a region associated with a distribution of electric charge or a varying magnetic field in which forces due to that charge or field act upon other electric charges.
Electric and Magnetic Constants In the equations describing electric and magnetic fields and their propagation, three constants are normally used...

At times the electric field itself may become detached from the source charge and form closed loops, as in the case of charges accelerating up and down the transmitting antenna of a television station. The electric field with an accompanying magnetic field is propagated through space as a radiat...
