Sure, that makes sense. However, my question arises when I physically see lines of flux when I scatter iron filings around a …

WebMagnetic fields are relativistic electric fields (ie. the creation of an electric field due to space contraction from moving charges), but this was not known until Einstein's theory of relativity. Before relativity was discovered, magnetic fields were known to be generated by current (ie. moving charges) or changing electric fields. Comment Web22 feb. 2024 · 4 Answers.
