| May 6, 2020 at 17:13 | comment | added | J. Murray | That's not what I meant, but yes, in a real current-carrying wire there is no frame in which both the electrons and protons are at rest. What I was saying is that if you observe a charged particle moving near a current-carrying wire, you observe a magnetic force on it; if you boost to that particle's rest frame, the magnetic force goes away (and is replaced by an electric force) but that doesn't mean that the magnetic field goes to zero. | |
| May 6, 2020 at 16:43 | comment | added | DatBoi | Moving charges create magnetic field. So in the first case, it is produced by the electrons moving. In the next case,the same magnetic field is developed by protons this time, is that what you're saying? | |
| May 6, 2020 at 16:40 | comment | added | J. Murray | @DatBoi When you boost to the rest frame of your charged particle, the magnetic field doesn't vanish - it simply does not exert a force on the particle because the particle's velocity is equal to zero. | |

| May 6, 2020 at 16:33 | comment | added | DatBoi | I must first appreciate the beautiful explanation given by you. In the third part of your answer, where you have mentioned that "If the EM field is purely magnetic in one reference frame, then you won't be able to find a reference frame in which it's purely electric." Well in my case where a charge is moving alongside a current carrying wire- from a frame at rest, the wire has neutral charge hence no electric force and purely magnetic. While the frame moving with the charge can account only electric force, hence purely electric. Am I going wrong somewhere? | |
