ABSTRACT:
Magnetic door hardware for closing swinging doors. Two magnets are axially aligned with the door post, and the magnetic fields of the magnets are aligned so as to produce a radial torque when the door is swung open. One magnet is attached to the door post, and the other magnet is attached to the door frame so that the radial torque produced by the magnets causes the door to rotate to the closed position.
