Question

Why does current generate magnetic field?

Answer 1

When a charged particle—such as an electron, proton or ion—is in motion,magnetic lines of force rotate around the particle. Since electrical currentmoving through a wire consists of electrons in motion, there is amagnetic field around the wire
