Electromagnetic induction, flux and flux linkage
... Magnetic fields are usually very symmetrical. Think about which parts must be just like others, or perhaps their mirror reflections when drawn in two dimensions. For example, the field of the coil below can be divided into four quarters, each a copy (reflected or inverted) of the others. So you only ...

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.
