Last week in lab you looked at the properties of static (time-independent) magnetic fields, produced by permanent magnets and by loops of current. These static fields varied throughout space in direction and magnitude, but were the same at all ...

A When thinking about current flow, think about fluid flow.
... •For there to be a current one cannot be at equilibrium •There has to be a potential difference, otherwise for every carrier moving in one direction another one is moving in the opposite •Think about fluid flow: there has to be a potential difference for fluid to flow otherwise water is stagnate. ...

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.
