Abstract
A magnetically levitating door is disclosed herein. The door may have a bracket having a magnet that is repelled from a magnet of a track. The magnet field of the bracket and the magnet field of the track may have different widths. The track may be disposed adjacent to a door opening. The bracket may have a guard in slidable engagement with the track to limit lateral movement of the magnet of the bracket disposed above and repelling the magnet of the track to levitate the door off of the track while preventing excessive lateral forces on the guard. The bracket may have at least one guide in slidable engagement with the track to secure the engagement of the bracket to the track and maintain vertical alignment of the bracket to the track.
