Deriving Coulomb's law and other fundamental equations from F=ma?

AI Thread Summary
Deriving electricity and magnetism from Newton's second law, F=ma, is not possible, as fundamental concepts like charge interactions and electromagnetic induction cannot be explained through classical mechanics. The discussion highlights that while F=ma is foundational for classical mechanics, it does not extend to electromagnetic phenomena. Instead, electromagnetism is better understood through quantum mechanics and its inherent symmetries. The conversation suggests that the joke about deriving everything from F=ma may only apply to classical mechanics. Ultimately, a deeper understanding of electromagnetism requires advanced concepts beyond Newtonian physics.

I saw a joke crib sheet for a physics class that said "F=ma, derive the rest," but is it actually possible to derive at least electricity and magnetism questions from Newton's second law?

No, you can't derive electricity and magnetism from Newton't equations. For example, there is no way the charge on an electron could be derived, nor could the fact that like charges repel and unlike charges attract, and nor could the fact that a varying magnetic field induces a current in a wire.

Not from Newton's law. But both the scalar and vector potentials are required if one demands the covariance of, say, Schrodinger's equation under local phase transformations of the wavefunction. Electromagnetism is ultimately explainable by a fundamentally quantum mechanical symmetry.
 
Perhaps they were just talking about deriving most of classical mechanics.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
