(Sorry my poor English) A changing electric field creates a magnetic field and vice-versa. I thought one field were created only when the another field were disturbed and it works finely for electromagnetic waves, and it agrees with Maxwell's equations. I was happy with my conclusion then I found a problem: a moving charge actually creates a magnetic field EVEN with constant speed, it breakes my conclusion apart, because in this case the electric field is not being disturbed and yet we have a magnetic field. How could it be?
