Step-by-step explanation:
Answer. The needle of a magnetic compass starts deflecting when it is kept nearby a wire through which electric current is flowing . 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.
