(C) current-carrying circular loop behaves like a magnetic dipole or a bar magnet. When a magnetic dipole is freely suspended in a magnetic field (like the Earth's magnetic field),it experiences a torque that aligns its magnetic moment vector with the external magnetic field. The magnetic moment vector of a current loop is perpendicular to the plane of the loop. For the magnetic moment to align with the Earth's North-South magnetic field,the plane of the loop must be perpendicular to the North-South direction,which means the plane of the loop will point in the East-West direction.

$A$ current-carrying circular loop is freely suspended by a long thread. The plane of the loop will point in the direction:
