| Apr 27, 2020 at 15:53 | comment | added | ACuriousMind♦ | I don't really understand what you're asking with "how did physicists know that the Force acting on a charged particle moving in a Magnetic Field (or a moving magnetic field in an electric field) will be a Cross Product?" - they didn't randomly invent "the magnetic field", they had observed the Lorentz force. What except the cross product formula with the magnetic field do you propose to explain the Lorentz force on a moving charged particle close to a magnet? Is "we know this formula is correct because it fits to observation" somehow not sufficient here? | |
