Lecture 8 Magnetic Fields
... • In ferromagnetic materials there are whole sections of the iron called domains where the magnetism does add up from individual electrons. Then there are other sections or domains where contributions from different domains can cancel. However, by putting the iron in a weak magnetic field you can al ...

The Unification of Electricity and Magnetism
... Abstract. It is widely believed that electricity and magnetism were united by James Clerk-Maxwell in the nineteenth century. In his 1865 paper ‘A Dynamical Theory of the Electromagnetic Field’ [1], Maxwell substituted the quantity ‘Displacement Current’ into Ampère’s circuital law and he obtained th ...

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.
