A tool changer in accordance with the present disclosure comprises: a housing fastened to a manipulator of a robot, wherein the housing is a non-magnetic material; a bar-shaped magnet disposed in the housing; a motor configured to rotate the magnet on a rotation shaft perpendicular to a longitudinal direction of the magnet; and a core configured to derive a path of a magnetic flux by the magnet. The core comprises: a pair of first poles facing both poles of the magnet, when the magnet rotates to be elongated in a first direction; a bridge configured to connect the pair of the first poles and disposed in the housing, wherein the bridge is a magnetic material; a pair of second poles facing the both poles of the magnet, when the magnet rotates to be elongated in a second direction perpendicular to the first direction; and a pair of terminals connected to the second poles and facing a magnetic body disposed outside the housing.
