Question

write down Maxwell equations in free space

Answer 1

The whole subject of electricity and magnetism may be described mathematically with the help of this four fundamental equations

Answer 2

Concept :

He described light as a propagating wave of electric and magnetic fields when he formulated electromagnetism. In general, he predicted that electromagnetic radiation would travel at a speed equal to the speed of light when combined with electric and magnetic fields.

Explanation :

Maxwell's first equation is based on the Gauss law of electrostatic, which states that “when a closed surface integral of electric flux density is always equal to charge enclosed over that surface”.

n an static electric field, the divergence at one point equals to the electric charge volume density ρ at that point divided by ε0.

Hence : The four Maxwell equations, corresponding to the four statements above, are: (1) div D = ρ, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J.
