Answer:

When the compass is placed below the wire, and the electric current switched on, the needle deflects in the opposite direction. If an electric current is passed through a long coil of wire (a solenoid ) a magnetic field is produced which is the same shape as that of a bar magnet.

Answer:

a changing electric field creates a magnetic field.

Explanation:

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).
