[QUOTE="Hiero, post: 6391122, member: 602040"] Everywhere I look online I see the formula for the magnetic field of a uniformly moving charge is, $$\frac{\mu_0 q \vec v \times \vec r}{4\pi r^3}$$ but when I calculate it by transforming the electrostatic field (taking the motion along x) I get, $$\frac{\gamma \mu_0 q \vec v \times \vec r}{4\pi ((\gamma x)^2+y^2+z^2)^{3/2}}$$ I can't find anything like this version anywhere. I just want to confirm that the version I keep seeing online is just the low speed limit where the gamma factor is approximately one? Or am I wrong? [/QUOTE]
