Does a moving charge create a magnetic field? At first the answer was obvious to me, since I = Q/t then if a charge is moved it is simillar to an electric current, and electric currents create magnetic fields. However in a conductor, an electric current consists of electrons moving past relatively stationary protons. So I know there is a physical difference between moving a charge and an electric current. I am just wondering what the differences are, my guess is that the faster a charged particle moves the electric field get weaker and the magnetic field gets stronger. But i haven't been able to find anything helpful for my understanding. If anyone knows of any explantions or concepts to help understand what happens it would be appreciated.
