... magnet in an arched pattern and show us that the effect of a magnet is strongest at its poles. In this picture, you can see the magnetic field because small pieces of iron have been placed under the magnet. The pieces align themselves along the lines of force and show us the magnet’s magnetic field. ...

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.
