The electromagnetic force is the second strongest of the four known fundamental forces. It operates with infinite range. All other forces (e.g., friction, contact forces) are derived from these four fundamental forces and … See more

In 1600, William Gilbert proposed, in his De Magnete, that electricity and magnetism, while both capable of causing attraction and repulsion of objects, were distinct effects. Mariners had noticed that lightning strikes had … See more

The Maxwell equations are linear, in that a change in the sources (the charges and currents) results in a proportional change of the fields. Nonlinear dynamics can occur when electromagnetic fields couple to matter that … See more
