CONSERVED CURRENTS OF THE MAXWELL EQUATIONS
... More than 20 years ago, Lipkin [4] found unexpected conserved currents, which led Kibble and Fairlie [5] to develop a method generating an infinite number of conserved currents. Anderson and Arthurs [6] have derived a Lagrangian for the Maxwell equations depending on the field strengths and not the ...

... Electrical current can be generated by moving a metal wire through a magnetic field. This applies both to alternating current (AC) and direct current (DC) electricity. This is a different method than where DC is created by a battery, which uses chemical reactions. It is also different than static el ...

... There exists a maximum value for the external electric field beyond which the atoms inside the material become ionized. The dislodged electrons (now free) give rise to a high current, which heats up, and eventually destroy, the material. This phenomenom is called dielctric breakdown. Dielectric brea ...

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.
