The Lorentz force law and the magnetic field
... This is the Lorentz force law. Notice that this is consistent with the deflection described above since the cross product v × B is always perpendicular to both v and B. Example: Motion of a particle in a constant magnetic field A particle of charge Q with initial velocity v0 moves in a constant magn ...

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.
