My professor said that the first two maxwell equation's are about static fields
Another fast question:
Do a single charge that is moVing generate a magnetic field?
I saw a demonstration that explains the magnetic field as an electric field using only special relativity, there is a free charge outside a wire, it is moving relative to the wire, there is current in a wire, a current is made with multiple charges and the lorentz contraction due to the relative motion makes the density on charges different, so there is like more electrons than protons according to the free moving charge in a section of the wire...
But how can this demonstration be done if there is no wire but just a single charge moving?
So there is our free charge and another charge moving...
There is magnetic field?
How can you contract a Charge? It's without dimension
Please help me make this clear
