How does a CRT monitor produces image on the screen?

Process of Producing Image on the Screen by a Color CRT Monitor:

A CRT monitor has an electron guns at its back. The gun fires an electron beams at once through a magnetic coil that aims the beams to the screen.

The screen is coated with a chemical called phosphors that glow when struck by electron beams. This phosphor coating is organized into grid of dots where smallest number of dots that can be focused by the magnetic coil at once is called pixel.
