Electromagnetism

Electromagnetism

Like gravity, electromagnetism also affects our daily lives in the sense that it includes both electricity and magnetism. At the highest level, it holds together the atoms and the molecules and at the subatomic level, it binds the negative electron to orbit its nucleus and pushes two electrons that are closely held in an atom apart so that they do not collide with each other.  Electromagnetic force came about with the efforts of James Clerk Maxwell 1864 to synthesis the laws of electricity and magnetism. His view is that light itself is both pure electricity and magnetism, or in short electromagnetic wave. According to the Standard Model of particle physics, electromagnetic interactions are mediated by photons, which are considered responsible for producing all electric and magnetic fields. While gravity is attractive, electromagnetic force can be attractive or repulsive depending on the charge of a particle and its range of influence is infinite. It is no weakling. It’s 100 times weaker than the strong interaction but 1,000 times stronger than the weak force. But as one goes down to the lower-level particles, the effect of electromagnetism can no longer be detected.
