May 20, 2023 at 17:22 | comment | added | Ghoster | The electric fields are actually magnetic fields and vice versa … there is no difference between them. That’s false. In mainstream physics they are not the same thing, and there is a difference between them. | |
May 20, 2023 at 17:07 | comment | added | Ghoster | That’s a terrible rendering. Look at the one on page 16 of this PDF. The electric and magnetic fields don’t look even remotely similar. | |

May 20, 2023 at 11:43 | comment | added | SnoopyKid | @Frobenius I'm sorry I don't understand the link at all because I don't have a background in mathematics. | |
May 20, 2023 at 9:59 | comment | added | SnoopyKid | @JeanbaptisteRoux sorry but actually I specifically talking about electromagnetic field like light, gamma ray, radio wave, etc. | |
May 20, 2023 at 9:46 | comment | added | SnoopyKid | @JeanbaptisteRoux you said "Concretely, an electric field will change the trajectory of a particle over time, while a magnetic field will change its trajectory over space." sorry I think there is some misunderstanding. You mean the electric field change the path of the particle over TIME, and the magnetic field change the path of the particle over SPACE. So, electric field determine how fast or slow a particle is and magnetic field determine the direction where the particle go? | |
May 20, 2023 at 9:30 | comment | added | Jeanbaptiste Roux | I already mentioned their difference, see the two first sentences of my first comment. Of course, since the Faraday tensor is, well, a tensor, its components mix up when doing a change of coordinate, like a Lorentz transformation for example. But this does not mean these two concepts are interchangeable or the same. I recommend you look at the Wikipedia entries Faraday tensor and Electromagnetism. | |
May 20, 2023 at 9:24 | comment | added | SnoopyKid | @JeanbaptisteRoux I'm talking from the perspective of people who think of the charges like electrons and protons as ball-like objects or particles. From the viewpoint of people who viewed charges as disturbances in the field, there is nothing that moves from this place to that place. So, in conclusion, from the perspective of those who viewed the "particles" as field disturbances, the electric fields and magnetic fields are the same and interchangeable. | |
May 20, 2023 at 9:00 | comment | added | Jeanbaptiste Roux | What I said works also for static electric and magnetic fields with respect to the charged particle. Also, I don't know what you mean by "moving": a field is a field, it fills the entire space-time and the propagation of waves in it is to be viewed as disturbances, not as a moving field. | |
May 20, 2023 at 8:45 | comment | added | SnoopyKid | @JeanbaptisteRoux "Concretely, an electric field will change the trajectory of a particle over time, while a magnetic field will change its trajectory over space." so both are basically moving. They are waving after all, right? Therefore, no real difference between them? | |
May 20, 2023 at 8:35 | comment | added | Jeanbaptiste Roux | The magnetic field components are the purely spatial components of the gauge curvature of the four-potential. The electric field components are the remaining ones. Concretely, an electric field will change the trajectory of a particle over time, while a magnetic field will change its trajectory over space. | |
