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.

When an electric current flows in an external magnetic field, it experiences a magnetic force, as in electric motors. The heat loss, or energy dissipated, by electric current in a conductor is proportional to the square of the current. A common unit of electric current is the ampere, which...
Macroscopic electric and magnetic fields and potential functions are usually defined as weighted averages of their microscopic counterparts. It is shown that this procedure is satisfactory for the field and the scalar potential due to electric point charges. When elementary electric dipoles are ...
Thepotential energyfor a positive charge increases when it moves against an electric field and decreases when it moves with the electric field; the opposite is true for a negative charge. Unless the unit charge crosses a changingmagnetic field, its potential at any given point does not depend ...
Proven fact: Every moving charge creates a magnetic field. Proven fact: The electron is permanent moving charge, thereby creating a permanent magnetic field. Is the electron’s permanent magnetic field any different from a macroscopic permanent magnetic field? Proven fact: Break a permanent magnet,...
