Chapter-8|Electromagnetic Waves|NCERT 12th Physics:
Maxwell’s equations are the basic laws of electric city and Magnetism.
All the basic principles of electromagnetism can be explained in terms of four fundamental equations call maxwell’s equations.
Maxwell did not discovered four equations, but he worked on them and stated that these four fundamental equations define complete electromagnetism.
1. Gauss’ Law in Electrostatics:
This law states that the total electric flux through any closed surface is always equal to 1/ε₀ times the net charge enclosed by that surface.
