... An electric field means that the interaction is not between two distant objects, but between an object and the field at its location. The forces exerted by electric fields can do work, transferring energy from the field to another charged object within it. ...

... Definitions: Electricity is the flow of electrical energy or charge. These charges move from one place to another in an electric circuit, carrying electrical energy. A circuit is the actual pathway the electricity flows along, from a power source, to where it is needed and back to the power source. ...

... Perfect Diamagnetism: Superconductivity • If a superconductor is moved into a magnetic field, the magnetic force on the moving charges generates currents at the surface of the superconductor—these currents produce a magnetic field exactly canceling the original field inside the superconductor. So ...

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.
