... Let’s compare the electric fields due to two identical surface charge densities σ, one on a conductor with all the excess charge on one side (e.g. the outside of a charged sphere) and the other on a thin insulating sheet. The figure shows a short “Gaussian can” straddling the thin charged sheet. If ...

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.
