By relativity+coulombs force, I worked out that the (magnitude of the) magnetic field of a charge Q moving at speed V should be (ϒVV/c2)Q/(4πε0r2) or in terms of mu, ϒVμ0VQ/(4πr2) (where the distance r is measured normal to V).
When I google the answer I only find the same thing but without the gamma factor. Did I make a mistake or are they just using the non-relativistic approximation ϒ≈1?
