### Insight

Can anyone please explain me some uses of maxwell's on my REAL life?
REAL life = weapons, propulsion, tech, radio frequency and microwaves,nuclear physics(maybe);
no REAL life = monopoles, origin of the universe, space bull, particle physics( muons,pions etc.);
PS. I am 14 years old so don't twist out of their proper order too much.

You might want to lose the 'tude, bro.

Anything involving electricity, magnetism, radio and light.

At this point in time the question is rather, what electrical device didn't have Maxwell applied during it's design? Antennas, RF interference etc etc are designed and vetted with those equations.

Not only that, but Ohm's Law and the Kirchhoff Laws are simplified solutions of Maxwell's equations, so anytime you use those, you actually use Maxwell.

How 'bout your cell phone, tablet and computer, not to mention the network you are sending the question on......

Maxwell's equations in materials can be used to help explain the physics of permanent magnets=it results in a formula for the magnetic surface currents which explains the magnetic field that gets generated as well as helps explain why the magnet remains magnetized. $\\$ It can also be used to explain how radio frequency waves propagate, which thereby makes communications of all kinds possible with TV transmitters and radio signals etc. $\\$ It also explains much of how light in the visible region will be able to create things such as interference patterns, which has many applications in optical technology.
