Why does electric current show magnetic effect?

  • Scientists have observed that a changing electric field creates a magnetic field. So, if you have a circuit and you send AC current through (AC = Alternating current) so that the electrons move back and forth, they will create a changing electric field. This produces a magnetic field (because that's what the universe does).
