Relativity is often said to explain magnetism. The usual claim is that magnetism is really just electrostatics seen from another frame.
But is that actually a deeper explanation, or does it only work after the current has already been idealised into a clean, neutral wire?
In this video, we look at the standard textbook explanation of magnetism and relativity, the role of moving charges, neutral conductors, electric and magnetic fields, the Lorentz force, and why the familiar wire example may hide more than it reveals.
The issue is not whether relativity can transform electric and magnetic fields between frames. It can. The deeper question is whether that frame transformation explains the underlying electrodynamic interaction, or whether it starts after the messy local process has already been averaged into sources, fields, and response laws.
We also return to Ampère’s original electrodynamics, where current elements interact directly through their geometry, and compare that with the modern Maxwell-Lorentz field picture. What changed was not just the mathematics. What changed was what physics allowed to count as the interaction.
