It was mathematical representation of the magnetic field that is produced by the electric field and only long derivation. But, still no answer why magnetic field is produced in the first place. It is like if someone asks why their is gravitational force between two bodies, and you give them the equation of gravitational force between the two bodies. This particular problem is with the whole education system. Instead of explaining the cause, people will explain the effect.

One answer can be: field is just 'possible force' - math description of force which will be present if moving charge is there. But I'm not satisfied with this because magnetic field is also reservoir of kinetic energy of moving charge - so this is real thing, exist without other charges around.
Dear sir, according to this theory, production of magnetic field due to a moving charge is completely a relativistic phenomenon, ok here is my doubt, that a charge is at a rest frame at origin, i m a in a frame which is moving in x-axis with velocity v , it seems that charge moving away from us with some velocity -v. I just want to know that in this situation still the charge particle produce magnetic field or not. Plz sir help me
Electromagnetism, like gravity, is a relativistic consequence. Given that like charges repel each other and opposite charges repel, you understand the cause by analyzing different reference frames
I have a question too In the above video he took gamma approximately 1 If gamma is 1 then whole thing should stop If gamma is 1, then force is s and s prime frame must be equal
@@theoreticalcmp Alright...I found the transformation of forces on Quora.(www.quora.com/Does-force-depend-upon-frame-of-reference) By the way, since frame S’ is moving with velocity v relative to frame S along X direction, should the equation be Fx = Fx' instead of Fx = Fx'/γ(at 2:32)?
In moving frame , Mass(relativistic) = m(rest)×Y ,where m(rest) is the mass of a body at rest . So F' = m(relativistic)×a and F(rest)= m(rest)×a ; then we can say F'=Y×F so F=F'/Y
Sirrrr... i have a question for u, we know that in electric field the main role is due to charges and in magnetic field we have the North pole south pole interaction but in case of gravitational field what is the medium i mean how a mass can attracts the other mass without any medium between them. Sir please 😫🙏🙏💓 answer me...

@@theoreticalcmp thank😊s now i understand spacetime cruve bend but i have more questions💭❓ How the heat (energy) can transfer from one point to another without any medium ?
Abhishek gautam its due to infrared radiation Infrared radiation from sun travels to earth at the speed of light (since its a electromagnetic wave) when the radiation strikes on any object it triggers the atom of that object which causes it to jiggle. And you might already know that heat is simply the kinetic energy present in the atom. So heat itself doesnt travel through empty space, radiation does which produces heat when it strikes on an object... Hope you get it.

Very good And does it mean İnto the natural magnets too there are Moving charges ?? This means magnetic field is not a separated thing from Electric field and all depended on transformation and reserving the Total energy amount
@@theoreticalcmp yea okey the moment of electrons Produces magnetic dipole moment When these moments are polarised in the same direction acts like field producer okey but still there are thing which i dont understand
@@theoreticalcmp that this means every matter Can be a magnet if some conditions are apropriate soo magnetic field acts like dictator he wants to make everyone looking same way 😁 But the force it produces Look like everytime magical thing because there is no contact force There is no carrier of force its magicaly in space 😁
Actually no. There is a career of electromagnetic field and you've heard the name of that career a thousand times just without realising that it's the career. The name of the career is 'photon'.
@@theoreticalcmp i mean there is the space between Magnetic field and iron And it atracts each other and pulls the iron without any contact force İ mean contact force Not carrier soory for the language mistakes And this property of magnetic force Also shows its nature about spacetime and fundemental things We dont know the Real answer even feynman said that
The magnetic field is and contain the Kinetic energy of the electrical field. At low speeds KE = 1/2 m v^2 the energy of the electric field is E= m C^2 so m = E/C^2. We know well how to calculate E . :
all this math is ok but its still doesn't answer the question why magnetic field is produced? In other words what really happens to the space around it...
A magnet is field coherence qualitatively. Fields make everything, a magnet has been made coherent to the fields from which is is made. A laser is made possible by coherent light- a magnet is the same thing.
Check this video: ruclips.net/video/1TKSfAkWWN0/видео.html It will be immediately clear what is happening and why magnetic field is created. Spoiler alert - magnetic field doesn't really exists, it's the electric field plus theory of relativity. It was made up to make calculations easier and explain weird force acting on charges.
@@rfly-fpv electric, dielectric, magnetic are roughly analogous to ice, steam, water- the field under different pressure modalities. Dielectric terminates into magnetism/magnitude/mass and electricity is a hybrid of the two but is a discharge. Right hand rule all the way.. magnets don’t attract, they are trying to erase space, magnetism is the dielectric field. The attraction we see is the spacial magnetism losing its fight to the dielectric/counter spacial- its pressure mediation, water flowing downhill. All mass is due to magnetism (counter intuitively pushing out spacially) and all “attraction/gravity” is dielectric acceleration to a null pressure point. A black hole is an object that’s magnetic push has given over completely to its dielectric field coherence- it is litterally terminating into counterspace. That’s the theory I love best until it’s proven to be rubbish, which I don’t think it will.
A really nice and conceptual question. See, in special theory of relativity, though the S' is moving along X-direction, still velocities along y and z direction changes, because, the main basic quantity of all- the TIME Lapse changes for whole frame. Hence, the acceleration is also changing. The force is nothing but mass×acceleration; and as a result, all components of forces do change. In short, force, and all quantities that deal with time, changes as time interval changes with respect to frame-change. Hope this clears your doubt. Thanks Anindya, best wishes.
@@theoreticalcmp What acceleration we see there? Uniform velocity also produces magnetic field. Isn't already explained that retarded potentials of electrostatic field are seen as magnetic field?
But suppose if S' frame is at rest and S frame is moving with velocity v then a person at S frame will see as if S' is moving and charge must create magnetic field but we know S' is not moving so, will there be any magnetic field by that charge in S' frame or not?
@@theoreticalcmp so relative to another observer which is stationary it will not see any magnetic field but since i am in motion i would, how come sir?
@@NinjaPlayer005 Think carefully: Your question has been answered properly. I think your question is if there is a current(i.e, moving electrons in general) there should always be a magnetic field irrespective of whether I'm moving with the electron at same pace or not!! Yes, that's also true as while you are moving with electrons, you're essentially moving wrt protons or nucleas which are charged particles. So, then too, the runner (wrt whom the electronons are stationary) will experience a magnetic field. However, for a particular charge or array of charge moving in free space will have the effect that has been answered and it's weird but true.
Electric fields is about the electric charge or the magnetic poles in motion. Magnetic fields is about the magnetic poles or the electric fields in motion. I don't say what charge/poles is about.
Thank you! But you have not given the answer. You used many triks (gamma=1 when you decided: that velocity of 10E-4 m/s from Solid Physics: adding the k versor at the "right" time)... Ok. the formalism may be right. But what about the fenomen? The World does exist grace to the Xs we put on paper?
A current carrying conductor placed perpendicular to length of a long rectangular loop ( width negligible to length, say 1: 20) the electrons in the conductor moving perpendicular to the conductor still experiences a force. The conductor moves perpendicular to its length (& perpendicular to length of the loop). How can this be attributed to Relativistic Effect.
So now the question is ...If charge is producing magnetic field then how can the observer sitting in frame S' even observe that ( if he has compass ) magnetic filed??? Because he is at rest w.r.t. both charges so he will observe only electrostatic force.
Well, let's take a wire. Free electrons are moving leaving behind the positive ions (which are much heavier and more or less, at rest). If a person moves with the same velocity of electrons, for him, these ions will be moving which in turn will result an experience of magnetic field. Okay?
Special relativity is only applicable for a body when it is in light velocity like 0.5c or something like that. Then when a charge is not in light velocity , what happens then?as far as I know charge in a metal moves in drift velocity which is too small in value.then how can we relate special relativity to explain magnetic field produced by moving charge?please explain.
Yes, we can. Special relativity is applicable for everything and only because c is too high, special relativity is neglected in lower velocities. Comparing the strengths of both electric and magnetic field, you will be able to get the answer.
See, when you are in motion, space contracts and time elongates. A popular phrase is, 'moving clock ticks slow'. Anyway, since space and time behave differently while the body is moving, definitely, in moving frame, force will also be modified. Calculations show this modification is exactly equal to the factor '1/gamma'

But, magnetic fields are formed from the aether by atomic alignment, which is permanent in a magnet, and temporary when electrons move in a line through the atoms of a conductor. Atomic alignment is key to magnetic field formation. Whichever method this alignment is achieved, the results are the same formation of the magnetic field, which is composed from the sorrounding aetheric medium which enters and exits every atom causing all to be in perpetual motion.
Check the difference between two "v", they two are only similar in magnitude and different in direction. When two vectors with same magnitude but different direction are multiplied via cross product, the result is not zero. Hope you understand.
Why make it complex for simple question? It is only two words, MF come from moving charges, which produces electricity, so it is result of two words, charges and motion, combine of them produce MF, so MF is three, so three in total that match parallel represent 3 numbers, would a person write alot of formula that would equal many numbers that is 3 * 2 = 6, is 6 numbers as PR, despite it totals 5 when add, but make more complex w/ multiply, so using higher numbers of assumptions to get right answers contradict to least assumptions make right, you make it complex from simple question, why?

Check the difference between two "v", they two are only similar in magnitude and different in direction. When two vectors with same magnitude but different direction are multiplied via cross product, the result is not zero. Hope you understand.
@@theoreticalcmp sorry for that i found the difference between those velocities those were Vi×Vj thnx for replying fast

Why make it complex for simple question? It is only two words, MF come from moving charges, which produces electricity, so it is result of two words, charges and motion, combine of them produce MF, so MF is three, so three in total that match parallel represent 3 numbers, would a person write alot of formula that would equal many numbers that is 3 * 2 = 6, is 6 numbers as PR, despite it totals 5 when add, but make more complex w/ multiply, so using higher numbers of assumptions to get right answers contradict to least assumptions make right, you make it complex from simple question, why?
I think you haven't understood the question in first place. We know that MF comes from moving charges but the question here is why.. ok dear? Probably it's time to go back to revision ..
@@theoreticalcmp Yea, but you answer with the complex process with math, but not a simple explanation, the simple process.
@@khaliffoster3777 I don't think it can be made much simpler. It's really a relativistic effect. Einstein said, " Science should be made as simple as possible, but not simpler."
@@theoreticalcmp So, you are saying the video is simple as you can make it by using alot of number as math to result, so that is your answer why by using math to show as right answer. Complex math.
