Magnetostatics -> Electrostatics?? I have a questions and I am afraid that I might look very dumb for asking such questions, so forgive me first. I heard many times how Maxwell's equations along with Lorents Force Law tells all the story of EM dynamics. So I wanted to see if I can show (by using four Maxwell's equations) a simple questions. Q: given "Magnetostatics", can I show "Electrostatics" must follow? By Magnetostatics, I mean dB/dt = 0. By Electrostatics, I mean dE/dt = 0. (Not samething as saying source charges are stationary!). So, simply, how can I show dB/dt = 0 -> dE/dt = 0 using Maxwell's equaitons. Thanks in advance. p.s. Just in case, if someone out there trying to tackle this question by employing Columb's Law, I must warn you that it is not one of Maxwell's equation. (I mean, you can't use it to show electrostatics, cuz you already have to assume electrostatic to use it!) I say this here cuz many of my friend's first response was so.
