A magnetic compass placed near a live electrical conductor will deflect due to the magnetic field produced by the current.

Explanation:
Current flowing in a conductor creates a magnetic field around it. A magnetic compass aligns with the local magnetic field, so when a live conductor is nearby, the compass needle will deflect as it responds to the field produced by the current. The deflection grows with stronger current and with being closer to the conductor, since the magnetic field strength increases under those conditions. The material of the conductor doesn’t change the fact that a magnetic field exists due to the current in ordinary cases, so the compass will still deflect.
