| 41. | :As in electromagnetism, the gravitational field depends on a retarded potential.
|
| 42. | In electromagnetism, one of the empirical facts in the history of physics.
|
| 43. | There is no difference between gravity and electromagnetism / light in this regard.
|
| 44. | The photon, for example, carries electromagnetism.
|
| 45. | A . Electromagnetism is the most familiar one.
|
| 46. | Theoretical physics has historically taken inspiration from philosophy; electromagnetism was unified this way.
|
| 47. | No electromagnetism is used to generate the magnets.
|
| 48. | For classical electromagnetism, it is Maxwell's equations that describe the dynamics.
|
| 49. | The concept of a potential occurs in fluid dynamics, electromagnetism and other areas.
|
| 50. | This Yang Mills theory describes interacting vector bosons, like the photon of electromagnetism.
