Classical electromagnetism and special relativity | 🗖 nosplit | ↑ parent "Special relativity" | 105, 3, 298
The Lorentz force makes no sense without special relativity, because different observers have different speeds, see e.g.: charged particle moving at the same speed of electrons thought experiment. o
When such though experiments are seen from the point of view of special relativity, it becomes clear that magnetism is just a direct side effect of charges being viewed in special relativity. One is philosophically reminded of how spin is the consequence of quantum mechanics + special relativity.
Actually, it appears that Maxwell's equations can be derived directly from Coulomb's law + special relativity:
