Abstract
A magnetic door closure apparatus includes a first magnet in a door frame and second and third magnets in a door. The second and third magnets align with the first magnet when the door is closed. The second magnet's polarity is the same as the first magnet, and the third magnet's polarity is opposite that of the first magnet. When the door is nearly closed, the distance between the first and second magnets is less than the distance between the first and third magnets. The magnetic attraction between the first and third magnets is large enough to overcome the magnetic repulsion between the first and second magnets so that the door can be closed and is large enough to hold the door closed, whereas the magnetic repulsion is large enough to prevent the door from slamming against the door frame as the door is closed.
