In a magnetic contactor, which part is attracted or picked up by the coil when energized?

Explanation:
When the coil is energized, it creates a magnetic field that pulls a movable piece toward the magnetic circuit. That movable piece is the armature. The armature is the part that is attracted and moves to operate the contacts, while the frame remains stationary and the coil just generates the field. The yoke completes the magnetic circuit and provides a path for the flux, but it does not move. So the armature is the part picked up by the energized coil.
