Electricity and Magnetism Summary Notes
... When electricity flows through a wire the wire can get hot. This can be dangerous as it can create an electrical fire. It is also used in electric fires, irons, stoves and light bulbs. As electricity can be dangerous we need a method to ensure that we stay safe even if something goes wrong. Also som ...

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.
