Thanks. Best explanation in KZfaq ☺️

The collaboration between Faraday and Maxwell has to be one of the most revolutionary partnerships in history.

I love how you articulate equation 3 and 4, which links to the unification beautifully, well done!!

Maxwell had 20 equations and Heaviside compressed them to 4 equations that neatly described the fields and their interaction. Heaviside was facinated by operators.

Thanks Paul a great video summarises all important points in an understandable way

4 years of electrical engineering and a lot of mathematics, I finally understood what is the electromagnetic field...

Thanks for your clear voice and good explanations.

Super great presentation. You got the right kind of character.

Amazing explanation! Thank you

Thanks. I'm going to use this with my class in the next few weeks.

great explanation - thank you so much :)

Great explanations and history!

I’m doing a project on Maxwell and this video helped a lot. Maxwell also went to the high school I go to as well

Thank you for this necessary video

Brilliant explanation of radio, I got to use this in practice while in communications in the military.

thank you so much sir! i appreciate all your videos!!

By far the best explaination.

Brilliant explanation of Electricity and magnetism by way of great examples thanks.

thanks much for these great videos!

Great video - I continue to struggle with Maxwell and most specifically the math - but your explanations are very helpful .

excellent stuff, thanks.

Thank you very much for the informative video

Thankx sir your presentation is good it help me A lot there is lockdown in America, so I watching your videos

Loved it!

As simple as it is the best explanation

very well explained.....

This basically summarised my whole course in a beautiful way

Thank you so much!

Thank you!

Most diagrams of the magnetic field lines in a bar magnet that I’ve seen, show the pole faces as the region where the flux lines are the most dense: Leaving the north pole face and entering the South Pole face. Thanks for considering.

Thx you explain it very well

Beautiful.. what a genius !

I might love this channel.

Well done

Thank you 💗

this helped lots with my understanding of Electromagnetic Spectrum Inquiry question: What is light? Students: ● investigate Maxwell’s contribution to the classical theory of electromagnetism, including: - unification of electricity and magnetism - prediction of electromagnetic waves - prediction of velocity (ACSPH113) Year 12 Physics Stage 6 Syllabus 59 ● describe the production and propagation of electromagnetic waves and relate these processes qualitatively to the predictions made by Maxwell’s electromagnetic theory (ACSPH112, ACSPH113)

Amazing stuff

thank you

Thank you sir

Einstein actually lent heavily on Maxwell's understudy Heaviside. Heaviside and the Maxwellian's took the notoriously difficult 20 polymath quadratic equations and rendered them down into just 4 . Not big and not clever. They omit the Electro-Gravidics (Gravity) part of EM, which is 2/3rds of Maxwell's work., which is why Relativity doesn't really fit/work/explain. In the next installment we can talk Zero Point Energy and the genius that was T Henry Moray.

Thank you

I'm big fan of James clerk Maxwell

this was great until the end where we look at em waves outside of visible light. There are 2 themometers at Greenich observatory that were used to identify/prove infrared radiation. Where do these fit in to this story? Cheers and thanks for the great explaination. Cheers Tom

What is the'' ocean'' for electromagetic waves? what is their medium? they run on what? Black water?

The constant c is constant to? To all inertial systems/to all emission systems/to all absorption systems/to the empty space/to the eater...

Thanks

Could the magnetic wave 90 degrees out of phase with Electric wave or is it actually perpendicular to the electric wave?

how a point charge is isolated practically ?

Wow! You got the 5stars.

I had no idea that Maxwell bought so much to physics . Always considered his work relative to transformers. It’s better to show as application of the physics formula to a practical application.

Kathy Loves Physics is doing a video on Maxwell's Equations now, and it will be posted in about two weeks. She is going to show the equations, and explain it all.

Could you present the history of measurements of epsilon (electric permittivity) and of mu (magnetic permeability)? Thank you in advance!

perfectttttttttt

What if the flux passes through the magnet in a figure eight passing from pole to pole like a sine wave in voltage with a negative and positive charge instead of circular "motion"? Then again, I don't know my adz from my elbow.

Scotland had other maths guru's Napier, Black, Hume, amongst others

This shows we are in a close space

"Doing the Math" is using Actual Intelligence to apply Superposition-point Singularity Positioning Thermodynamics, (kinda like Algebra because it is more qualitative in character), and by default, balancing the Supersymmetry of dualistic time-timing cause-effect sync-duration connectivity. Ie Quantum-fields pulse-evolution analysis by Observation and it's actually what is REAL genius in the Mind-Body re-cognition of Actuality Conception sense.

My physics professor send this to us and now we're here😅

Heaviside's Equations. Since Maxwell's quaternions were just quaternion math applied to descriptions of already-known physical effects (Gauss' Law, Gauss' Law for magnetism, Ampere's circuit law, Faraday electromagnetism effects) it's puzzling Maxwell gets all credit for Heaviside's work and no one has ever heard of the author of the 4 equations. Sometimes I wonder if the science community felt sorry for Maxwell passing on so young and over-bestowed credit. Should be known as Heaviside's Equations. No one today is actually using Maxwell's quaternion math. In the classroom, Heaviside's four equations are taught. Maxwell added some rigor to Gauss/Ampere/Faraday but his math was not feasible, the utility value was low. Heaviside's 4 equations are incorrectly known as 'maxwell's equations' We are all using Heaviside's Equations. I bring it up because it's very disconcerting to younger contributors, the risk of putting in so much effort only to have a substantial contribution like that of Heaviside - completed uncredited. Why do the work. We need motivated young people. . .

(FREE SPACE) was mentioned. Is that SPACE infinitely full of energy/information?

How can we define a manifold..in simple wording with at least three examples.

I never understood why Maxwell did not receive the Copley Medal.

Nice Maxwell now I know

Another issue with this lesson, a magnet has 4 poles, 2 strong and 2 weaker field emanating from the side of the bar. Earth has 2 poles North and South and has 8 smaller poles.

His name is spelled James CLERK Maxwell, but it is pronounced James CLARK Maxwell. Sometimes in the video it is pronounced correctly, others not.

why does earth spin east to west when tole poles are north to south ...

Do mathematical descriptions really yield understanding of a phenomenon? If you formulated a set of equations that successfully described a child's behavior, would that give you a real understanding of the child? Or is true understanding on a different level, or of a different type?

Thanks BC

I wish I spoke Math.

🤗🤗

Maxwell rejected Grassmann’s current elements force law, which is Lorentz force law for magnetostatics, since Grassmann’s force law violates Newton’s third principle of motion. Maxwell died before he could publish on his own ideas on the correct magnetic force law, so we stick to the Lorentz force law today. Whittaker continued Maxwell’s unfinished analysis of Ampere’s current force experiments, and came up with Whittaker’s force law of electrodynamics, but he did not show how to integrate his more general force law in a generalised electrodynamic field theory. I showed in how to this in 2016, see my paper on General Classical Electrodynamics. My theory is the only theory that allows for the ‘non relativistic’ derivation of E = M c^2 without the notorious incorrect 4/3 factor.

I wish I was half as smart as James Maxwell.

9:18 "If you start with a charge and move it up and down ..." If you start with a charge then you start with an electric field. One cannot exist without the other. 9:26 "This wave would require no medium..." Of course this makes little sense since each movement of the charge is inducing both an electric and a magnetic field. Fields are mediums.

Nice Maxwell now I kno

Einstein's R + 1/2 Rg = 8πG/c4 T How did he know it was 8? And not 9 Einstein appraised Maxwell for being his foundation, I agree. I know Einstein was a master 33. He was created and sent for a purpose. He was a abnormal human with a evolving singularity"great heart" instead of friction of polarities as a normal human. Same as the three waves of volunteers. One's purpose is purpose of another. I understand the 8 but I don't understand how he knew in 1900's Even to this day it's unknown to the world or is it. I would appreciate if a normal person to enlighten me, 8? Telsa was his polar opposite. All greats has one

Teach me pleaseee

9:30 love your videos but saying that there are waves that move without a medium is a contradiction by itself! The definition of wave is a movement in a medium.

Hello doctor, I am a student from Iraq from the college of pharmacy, first stage because of the bad conditions in the world. He asked me to report on being evaluated for me and given me a degree for it before the final exam. It was the subject of my report on (The theory of electromagnetic waves) I hope that you give me the source I prepared from the lecture to write about my research and present it to my doctor, thank you doctor

I knew all this when I was twelve years old. How about something a little more advanced?

I heard Maxwell was a Clerk

Maths

you like every one repeat current belief. Maxwell is wrong in combining magnetic flux with elector static field. magnet permeate in free space electric field need a conducting surface and therefor can not be treated the sarrive

Hello, my name is William. I am an American PhD physicist and I have been investigating propagating Electromagnetic fields for many years. My investigations revealed that these fields and the information in these fields propagate nearly instantaneously when they are created and reduce to the speed of light as they propagate into the farfield. For more information, Google search William Walker Superluminal. According to Albert Einstein, if the speed of light is not a constant, then his theories of Special and General Relativity are wrong. This can be seen in Einstein's time dilation result due to a moving observer: t=r t' and the length contraction result: L=L'/r, where t and L are reference to the stationary frame, and t' and L ' are reference to the moving frame, and r is the Relativistic gamma factor: r =1/Sqrt(1-(v/c)^2). These results are easily derived using Einstein's light clock thought experiment using simple algebra. But if propagating EM fields with infinite speed near the source are used in the derivation, then c = Infinity, and r=1. If propagating EM fields far from the source are used, then c = the speed of light, and r= the standard Relativistic gamma factor. What comes out of this is that the effects on time and space are completely different depending on whether one uses propagating fields near or far away from the source, which can't be true since time and space are real. So the conclusion must be that Einstein's Relativity is wrong and time and space do not change with respect to moving reference frames, Galilean Relativity is correct, and that Einstein's equations just enable us to back calculate to the correct answer, given the time delays observed by the propagating EM fields used in measuring the effects. For more information, Google search: William Walker Relativity. But these results do not account for the time dilation observed by moving atomic clocks in airplane experiments, but can be accounted for using variable light speed theory (VLS), originally proposed by Einstein, and later improved by Robert Dicke in 1957. In this theory, spacetime is not curved by gravity as suggested by General Relativity, instead Newtons theory of gravity is correct and the many other known effects of gravity are due to the affect of gravity on the of light speed. For instance the observed bending of light by mass, which caused General Relativity to be accepted, can be explained, by the gravity generated by the mass, changing the speed of light, causing the light to bend around the mass. This effect is analogous to the bending of light in glass. Since lasers are used in atomic clocks to measure time, then the observed time dilation in atomic clocks in moving airplanes can be explained as due to the effects of light speed changes in the clocks due to changes in gravitation as the plane goes up and down. It should also be noted that several researchers have shown the relation E=mc^2 can be derived without Relativity using Newtonian mechanics, and the Michelson Morley experiment can be explained using the Doppler effect, ref Nathan Rapport 2021 In summary, this research shows that Einstein's theories are wrong and that time and space do not change with respect to moving observers, Galilean Relativity is correct, Newtons theory of gravity is correct, and many of the other effects of gravity can be explained as gravity simply changing the speed of light. The importance of this research is that it completely changes our understanding of time and space and gravity, and simplifies our theories. Perhaps this new understanding will finally enable researchers to finally unite Gravitational theory with quantum mechanics which have been incompatible since scientists accepted Einstein's theories for Special and General Relativity. For instance, Relativity is incompatible with quantum entanglement, which requires communication faster than light, but can perhaps can be explained by superluminal propagating fields between entangled particles. It should be mentioned that this superluminal effect is also observed in the propagating gravitational fields generated by an oscillating mass using Newtonian gravitational theory, and is nearly infinite near the source and reduces to speed of light far from the source. For more information, Google Search William Walker Gravitation. This matches very well with observations of the stability of the planets, which would not be possible if gravity propagates at light speed, and was originally proposed by Simone Laplace in his famous book: Mécanique Céleste in the late 1700's, where he estimated the speed of gravity to be 7x10^6 times greater than the speed of light. See: Wikipedia Speed of light. William Walker, 2 July 2023, Fjugesta, Sweden

Somewhat inadequate. Say you take a charged hollow sphere and move it at a non relativistic speed. There will be generate a magnetic field around the charged sphere. Now call the energy of the electric field E, you will find the energy of the magnetic field as B = 1/2 E/C^2 v^2. ( v is the speed of the sphere and C the speed of light) . Now if you take a rocket and follow the Sphere at the same speed v and then measure the magnetic field you find there is no magnetic field around the sphere when you hold the same speed as the sphere. Hmmmm, let's take something with the mass M and move that at the speed v it has a kinetic energy Es = 1/2 M v^2 , compare it to the magnetic field you realise that the magnetic field energy is the kinetic energy of the charged sphere. The mass being m = E/C^2 . And like kinetic energy of the mass M will become zero if you hold the same speed.

So let me get this right, Maxwell came up with the speed of light in the 1800s. Doesn't the great Pyramid have the speed of light incorporated in it. And yet our ancestors are supposed to be sooooo primitive. Yer right how about absolute genius.

I understand nothing . This is like the 20th video I watch but i just dont understand

Young

The potato is electric

Learn how to normalise audio! Your intro jingle damn well near ruptured my ear drums!

But there is a medium, otherwise what is waving? You can't say the field or the field lines. These are mental constructs or models of some reality. We need that reality, cannot hide behind words.

Not accurate information

blah blah blah
