Magnetism
... This additional force is called the magnetic force. All magnetic forces are caused by the motion of charged objects. This means that even the magnetic effects of a bar magnet are caused by moving electric charges. But how could that be? You don't plug in a bar magnet! The answer has to do with the f ...

16.3 Ohm`s Law / Energy and Power / Electric Meters
... In order for current to flow through a circuit, you must have a source of potential difference. Typical sources of potential difference are batteries (which are just two or more cells connected together), and power supplies (electron pumps).

Meaning of Electric Field
... Electric field is a vector field, i.e., a region of space that has vectors associated with each location. The direction of the vector is the direction of force a positive test charge would experience at that location. The magnitude of the vector is the force/per charge a test charge would experience ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
