Hi guys I'm confused about Maxwell's equations, why does a steady electric current produce a magnetic field but a steady "magnetic current" doesn't? Like why is there no J-ish term in Faraday's law? I know the go-to answers like "because magnetic monopoles don't exist" but I'm not seeing the intuition there.

So the only way to create time varying electric fields is time varying magnetic fields, and the only way to do that is to put a ""steady"" current through a wire (what about non-steady currents, like what does that mean)? But I thought movement is relative? I don't get it.
