As I understand it, a moving charge produces a magnetic field. Now it may be that I have have a misunderstanding here and if so I need to have the proper understanding of this. So if I do have a misunderstanding here could someone correct me on this. Based on my current understanding though my question concerns moving charges and why they're not producing measurable magnetic fields. Let me give two examples.
Example 1 - The Mir space station is moving through space relative to earth at a speed of roughly 7660 m/s. That's quite fast compared to most moving things here on earth. It has a mass of 450,000Kg. That's a ton of charges all moving together as one. Mass obviously is composed of things like protons and electrons which are charged particles. Doing a rough estimate that is 2.56 x 10^32 charged particles moving through space quite fast. With that amount of charge moving that fast why don't wee see a magnetic field coming off the space station?
Example 2 - The moon doesn't have a magnetic field based on current measurements. Obviously there's quite a bit more charges comprising the moon than even the Mir space station. It moves through space relative to earth at roughly 1000 m/s. That's a bunch of charges moving at a decent clip. Why don't we observe a magnetic field associated with the moon?
