Humans are beings of light slowed down to a solid form by gravity and magnetism

The only two fundamental forces of nature that human beings can directly experience through their five senses are gravity and light.
 
The other sensations such as smell, heat, sound and so on detect macroscopic properties of matter, and not its fundamental forces or constituents.

Electricity is deeply linked with light. It is the accelerated movement of electric charge that is responsible for the generation of light

Atomic Theory

A theory of the nature of matter

 
All matter are composed of minute particles or atoms of a comparatively small number of kinds , all the atoms of the same kind being uniformed in size, weight and other properties. Based on the experimental and theoretical considerations, holding that every atom is composed essentially of a small positively charged comparatively heavy nucleus surrounded by a comparatively large arrangements of electrons.

In physics, the Faraday effect or Faraday rotation is a Magneto-optical phenomenon, that is, an interaction between light and a magnetic field in a medium. The Faraday effect causes a rotation of the plane of polarization which is linearly proportional to the component of the magnetic field in the direction of propagation.

Discovered by Michael Faraday in 1845, the Faraday effect was the first experimental evidence that light and electromagnetism are related.   Wikipedia Quoted.
