- 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.

Very good explanation
Greeting from Ireland. I just subscribed. Thanks for tutorial.
Hello there! Thanks for subscribing. Enjoy our content :)
The best .. no other words .. the best explanation ever🙏🙏🙏🙏🙏
Absolutely!!!
A little known attribute of dielectric fluids, which Maxwell thought space to be, is that they develop charge separations as they flow. A divergence in flow creates negative charge and convergent flows create positive charge. This is a physical phenomena which oil industry has to account for.
Space is a dielectric fluid. A perfect insulator which means that charges are held extremely locally. All of QM, integrating gravity, can be modeled using hydrodynamics of a perfect dielectric fluid of variable density.
Variable density? Yes. The density of space can be measured by the local energy density. We know from the mass energy conversion equation that although energy usually does not impinge on spacetime to the same degree as mass, this is because mass is in fact energy in orbit around itself and thus extremely concentrated.
Best video on the topic
Definitely a quality teacher.
BRILLIANT !!
I am not expecting this is very super explanation thank you 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.
Yes but if we visualize the whole loop, then they appear to start from North and end at South outside the magnet.
@@TheSecretsoftheUniverse But that's a problem I'm telling you about. You're treating two poles of magnet as separate, but there's no such thing as magnetic monopoles, therefore you can't treat them like that, also if you 'theoretically' separate two poles of magnet to distance then matematical dipole moment would look different than in ordinary matter. There's no such thing as "divergence in north or south pole of magnet", because if it would, then i can draw a different sphere and then divergence wouldn't be zero.
excellent
Very well explained!!👏👌.... waiting for more such videos
Thank you Divya
Great content sir... please upload more videos related to electrongantism and optics basic theory and model.
Thank u sir
Yar kamal❤
Very good
A photon can be seen as the spherical implosion shockwave caused by the collapse of an electron orbital. Electron shell shrinks, space rushes in creating a spherical implosion ripple which propagates from origin at c. This is the entire probability sphere of QM model as a physical event. The wavelength is the thickness of the expanding membrane. And consider that the outside of a sphere is always divergent relative to the interior side.
Explained in practical manner. That's make easier tq......
You're welcome :)
Wow 👌 such a brilliant explanation sir i love u really u are a legend
And u give me a lot of inspiration 🥰
Great illustration !
Can you just present some example problems and the ways of solving them please ?
Thank you so much for your kind efforts in enlightening us !
Liked and subscribed. Would have like to see some lab-examples or examples from the world at large. As it is, it seems more like repeating that is written on the board. But good effort no doubt! Do you have any videos on how these equations helped Einstein form the theories of relativity?
Also, why we have to use the termC squared,where c is the velocity of electromagnetic waves , to balance the fourth equation is not clear to me. The first 3 equations are straightforward because they are taking about fields. What is the reasoning behind using the wave velocity in the fourth? We were talking about fields in the first 3 equations, suddenly, in the fourth, we are dealing with wave velocity. How come?
A good start !!!👏👏
Thanks Abhijeet :)
thank you sir ji 🤩😁
Please make more videos on typically physics concepts. .we are waiting for those.
Sure Deepshikha :)
Tq so much sir... Sir can u plz explain more elaborately on this topic once again🙏🙏🙏
Very good young teacher. As everyone including me is in the process of learning so would like to suggest a key correction here that unlike electric dipole there is no such thing as sink or source for magnetic dipole say bar magnet. If you draw the magntc field lines also inside the bar magnet, they will just make loops. These curl.
Excellent and easy to understand explanation. Question If I have a specific question regarding Physics how will you answer or is there a platform where we can ask questions and get answers from you?
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🧎🏽♂️🤧
A video of the math explaining it’s significance and all
It's awesome explanation sir🙏
Thanks Anurag
Great explanation Sir!
Thank you Sidharth :)
Aaaa alot more to learn to digest this topic
Amazing gentleman, you explained the Maxwells equation with great excellence. I am interested to know the impact of the magnetic field on magnetic nanoparticles if put in the influence of the magnetic field, would you like to prepare a video on it. particularly when MNPs are in body tissue and both kept in magnetic field. Lahore, Pakistan.
Please upload more lectures
This is not important because Seagan said so...... But Maxwell was a Genious who grasped by intuittion how electricity is generated by the Magnetic Field and put this into mathematical equations..... so the world can use it....even Faraday who showed him by experimentaion didn’t understand how it did happen. As said so by Maxwell himself in his super work: The dynamical theory of Electromagnetism.
He said to understand how the magnetic field worked he needed a leap of faith in the fact that “the field always seeks a balance with the surrounding environment”. And his drawing of the sperical harmonics of the Earth is another genious work.
I wish I had seen your videos in college! You explain well
Good explanation bro... A small request could you make video on signals and system, Fourier series, transform, laplace and z transform...
Nice
Thank you sir 🙏
You're welcome 🎉
Great explanation Rishabh, keep it up
Thanks Ankit :)
Thank you for the simple but great explanation. Can you please also explain how maxwell was able to predict using this equation that the time-varying electric field will create a time-varying magnetic field and the combination of both these can propagate as an electromagnetic wave? Especially the last part regarding wave propagation. This was proved later by Henrich Hertz
Respect sir ❤❤❤❤
This channel is awesome..
Thank you 💕
U r amazing sir..Kash me ye video engineering me dekhti.....anyways it helping me now for technical exams
You're welcome :)
Good one!👍
Thanks!
what will happen if i imagine a gaussian sphere encompassing only south or north pole of a magnet...how can we explain the zero divergence condition i.e. no source or sink of magnetic field at any pole of a magnet?? Are the magnetic field lines accumulating at the poles or it passes contiounsly through the whole magnet?
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.
I think it would be cool if you made a video about the original 20 Maxwell equations.
So that in Faraday’s Law on the right hand side of the final equation the second term is equal to the negative of the first term and their sum is 0.
Thanku sir
Make a video on physical interpretation of wave propagation and radiation
Sir loading condtion of transmission lines derviation
Sir, what is the important difference between maxwell equation of electric field created by charge distribution and electric field created by time varying magnetic field.
Sir magnetic field me source or sink exit krte hai??
