Electric fields are produced by electric charges, and magnetic fields are produced by the flow of electrical current through wires or electrical devices. ... As current moves through a power line, it creates a magnetic field called an electromagnetic field.

Are electric and magnetic fields the same?

3) Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. (This is why physicists usually refer to "electromagnetism" or "electromagnetic" forces together, rather than separately.)

Are magnetic fields electric fields?

A magnetic field is not just an electric field with relativity applied, i.e. an electric field viewed from the wrong reference frame. In reality, a magnetic field is a fundamental field which can exist in a certain reference frame without needing any help from an electric field.
