The magnetic field generated by a flow of electrons in a vacuum is influenced by both the current and the speed of the electrons. Higher electron speed results in increased current, as current is defined by the charge per unit time (Q/t). Therefore, both the speed of electrons and the amount of charge contribute to the strength of the induced magnetic field. It is suggested that a smaller number of faster electrons can produce the same magnetic field as a larger number of slower electrons. This relationship highlights the interplay between electron speed and magnetic field generation.
