The Physical Meaning of Maxwell's Equations | The Secrets of the Universe

The Maxwell's Equations are four coupled differential equations that describe the behavior of electric and magnetic fields. Carl Sagan once said, "Maxwell's equations have done more good to mankind than any 10 Presidents combined". This quote shows how important the Maxwell's equations really are. Maxwell himself did not come up with these equations. He combined these 4 equations to prove that light is an electromagnetic wave. In order to understand Maxwell's equations, we must know what is divergence and curl.

1. Gauss' law in electricity: The Gauss' law in electricity states that the the divergence of electric field is directly proportional to the charge density. This law says that isolated positive or negative charges are responsible for electric fields.

2. Gauss' law in magnetism: The Gauss' law in magnetism states that the divergence of magnetic field is zero. This means that magnetic monopoles cannot exist.

3. Faraday's law: One of the most important equations in history, the Faraday's law states that a time varying magnetic field can produce an electric field.

4. Ampere's law: The Ampere's law gives a relation between the curl of the magnetic field and the current density. There was a theoretical and experimental flaw in Ampere's law. Maxwell corrected Ampere's law by adding another term to it.

Most satisfying video i've ever seen on YouTube explaining physical significance of Maxwells equations in such a beautiful and simple manner. Thank you Sir.

This is among the best introductory explanation of Maxwell’s equations I’ve ever come across, on a par with that by Richard Feynman! It’s really brilliant. Congratulations! You must be a fantastic teacher. I hope your students know how lucky they are! Best wishes from Australia.

Brilliant explanation of Maxwell’s equations by Rishab from “Secrets of the Universe”! Love the way he connects the physical manifestations of Gauss’s, Faraday’s and Ampere’s laws in a neat story! What a great teacher!

[reeselebbing]

Best, most clean-cut, explanation of Maxwell's laws!!! Thank you!

[firebirdies]

The best tutorial ever. Please make it a playlist 🙏

[jkimmels]

Thanks for sharing such rich insights! You seem to be one of the rare types who has the capability of understanding high-level concepts, yet has the ability to simplify things in a manner that those of lower capability (or less experience) can grasp. Thanks so much!

I have been following since 2015. now I am seeing you live... You are doing a very very great job.
You are my spiritual Teacher.
Respect from Pakistan.

Easiest video ever on maxwell's equation

[MrTomasino]

amazing video, thank you so much. Makes uni in quarantine a lot easier

[dewashishkumar]

Glad to see you sir I always imagined whose voice is behind these videos who explains things very clearly I like your videos and way of explanation and. Please keep going and enlight people with great knowledge god bless you and thank you for giving us intrsting secret of universe

[dhavid__]

Not me trying to find other related videos to the rigorous maths related to maxwells equation😩 this is the sweetest and most soothing explanation I’ve seen. You’d have gone further sir🧎🏽‍♂️🤧

[legendarysuperherotv]

i am very satisfied with the brief explanation of Maxwell equations. Thank you SIR

[namogh]

Your way of explaining is splendid sir. I wish you upload many more videos and keep us helping via your theories sir

in case of divergence of magnetic field - little correction: magnetic field lines did not start nor end in magnet, they go through - they are loops (continuous closed). Law says that there's no 'point' source of magnetic field.

[ambatipudimadhu]

Splendid explanation. Concise and beautiful.

[RyanJumarPantoja]

Great explanation.... I easily understand how each equation works....

[soniaboora]

Most satisfying Awesome explanation of divergence thax a lot dude

[RahulRaj-xmbu]

Good start bhaiya

I was waiting for your lecture series...
Lots of love ....
Pls do make videos on SPHERICAL HARMONICS

[gowri]

I am very thankful to you for this video.
Yours explanation is awesome and it gives clear observation.

There is a problem with the equation for the divergence of vector G. In fact, the divergence of a vector is a scalar quantity. However, on the blackboard, the divergence of G appears as a vector, improperly including the unit vectors i, j and k.
