| Maxwell's theory of electromagnetism, for example, united the previously disjointed phenomena of electricity and magnetism. |
| For electromagnetism, the coupling constant is proportional to the square of the electric charge. |
| One of the first topics he studied, which developed from his early work on electromagnetism, was a new topic, now called the fractional calculus. |
| The most familiar, and second strongest, force described in the standard model is electromagnetism. |
| Heath classes them as dealing with energy transfer, electromagnetism, mind-matter interplay, and acausal factors. |
| For the remainder of his life he sought without success a unified field theory embracing electromagnetism, gravitation, and quantum mechanics. |
