... Two weeks ago, you saw how a permanent magnet exerted a force on a current-carrying wire (and vice versa). In that lab, the positions of the wire and magnet were unchanged and the current was constant (except when you varied it to see how the force changed). So both magnetic fields were unchanged, r ...

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.
