... near it. The solenoid exerts a force on the compass or magnet, and therefore it also feels a force due to the presence of the other magnet (Newton's third law, right?). But if you turn off the flow of current, there's no force. It seems like we have two kinds of objects that act similarly, magnets a ...

Magnetism Review
... 27. “All magnetism comes from electric currents.” Is this statement true? Explain. Not to beat a dead horse, but this fact lies in the structure of the atom and how full the orbitals of electrons are. The magnetic field produced by natural objects comes directly from these electrons exerting an unba ...

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.
