# Feynman’s different approach to electromagnetism

We discuss a previously unpublished description of electromagnetism developed by Richard P. Feynman in the 1960s. Though similar to the existing approaches deriving electromagnetism from special relativity, the present one extends a long way towards the derivation of Maxwell's equations with minimal physical assumptions (in particular, without postulating Coulomb's law). Homogeneous Maxwell's equations are, indeed, derived by following a route different to the standard one, i.e. first…

We reply to some comments made by Davis (2020 Eur. J. Phys. 40 018001) on our paper (2020 Eur. J. Phys. 41 035202), by arguing that Davis’s assertions are unsupported in some cases and are…
