... e. The current in the coil is called the induced current because it is brought about by a changing magnetic field through the coil. There is no battery in the circuit. Yet, charges are moving through the wire. There must be a force doing work on the charges. Further experiments show that the charges ...

... The conducting sphere of an electroscope is loaded with charge q so that the conducting leaves stand apart as shown in Figure I. As a rod with charge QA is brought near (but does not touch) the conducting sphere in figure II, the leaves move towards one another. This rod is removed and a different r ...

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.
