The existence of a magnetic field around a current-carrying conductor can be demonstrated by placing a compass near the conductor. When current flows through the conductor, it creates a magnetic field around it. The compass, which has a magnetic needle, is sensitive to magnetic fields. The needle aligns itself with the magnetic field lines. If there were no current in the conductor, the compass needle would align with Earth's magnetic field, pointing toward the magnetic north. However, when the current-carrying conductor is placed near the compass, the magnetic field generated by the current can disturb the compass needle alignment, causing it to point in a different direction. This deflection proves that the current-carrying conductor has created a magnetic field around it.
