Answer:
If you hold a compass near a wire through which current is flowing, the needle on the compass will be deflected.
Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing.
The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow.
