A magnetic door stop/latch contains a first magnet mounted on or within a door and a second magnet mounted on or within a structure opposing the door, such as a wall, door jamb, door frame or baseboard. When the door is moving towards the opposing structure, the magnetic door stop may used to prevent the door from slamming into the opposing structure by virtue of the repulsive forces of the magnets. The magnetic door stop may be switched from repulsive configuration to an attractive configuration that holds the door in position.

1. A magnetic latch for releasably securing a pair of relatively movable components one to the other, and operable between a secured condition and a released condition, comprising: a first magnet housed in a rotatable mounting, the first magnet having a longitudinal axis extending between a first end having a first polarity and a second end located opposite the first end and having a second polarity,a second magnet housed in a second mounting, the second magnet having a second longitudinal axis extending between a first end having a first polarity and a second end located opposite the first end and having a second polarity, the longitudinal axis of the second magnet being co-axial with the longitudinal axis of the first magnet, such that the first end of the first magnet having a first polarity is in a facing relationship with the end of the second magnet having a polarity attractive to the first polarity of the first end of the first magnet to secure the pair of relatively movable components in the secured position,wherein to release the pair of relatively movable components one from the other, the first end of the first magnet housed in the rotatable mounting is rotated about an axis perpendicular to the longitudinal axis of the first magnet to bring the first end of the first magnet out of attractive condition with the end of the second magnet; andwherein, in operation, the second magnet does not move within the second mounting in which it is housed. 2. The magnetic latch of claim 1 further comprising a knob assembly attached to the rotatable mounting in which the first magnet is housed. 3. The magnetic latch of claim 2, wherein the knob assembly is attached to the rotatable mounting by a post. 4. The magnetic latch of claim 3, wherein the post is positioned perpendicular to the longitudinal axis of the first magnet. 5. The magnetic latch of claim 4, wherein the post is co-axial with the axis perpendicular to the longitudinal axis of the first magnet. 6. The magnetic latch of claim 2, wherein the knob assembly comprises a bushing. 7. A magnetic latch for releasably securing a pair of relatively movable components one to the other, and operable between a secured condition and a released condition, comprising: a first magnet housed in a rotatable mounting, the first magnet having a first pole with a first polarity and a second pole located opposite the first pole and having a second polarity opposite the first polarity;a second magnet housed in a second mounting, tie second magnet having a first pole with a first polarity and a second pole located opposite the first pole and having a second polarity opposite the first polarity;wherein when the pair of relatively movable components are in the secured condition, the first and second poles of the first magnet and the first and second poles of the second magnet are all aligned in a common axis, and when the pair of relatively movable components are in the released condition, the first and second poles of the first magnet are rotated about an axis perpendicular to the common axis out of alignment with the first and second poles of the second magnet; andwherein, in operations the second magnet does rot move within the second mounting, in which it is housed. 8. The magnetic latch of claim 7 further comprising a knob assembly having a bushing attached to the rotatable mounting in which the first magnet is housed. 9. The magnetic latch of claim 8, wherein the knob assembly is attached to the rotatable mounting by a post. 10. The magnetic latch of claim 9, wherein the knob assembly is mounted perpendicular to the common axis. 11. The magnetic latch of claim 8, wherein the knob assembly comprises a bushing. 12. A magnetic latch for a pair of relatively movable components one to the other, comprising: a first magnet housed in a rotatable mounting, the first magnet having a first pole with a first polarity and a second pole located opposite the first pole and having a second polarity opposite the first polarity, anda second magnet housed in a non-rotatable mounting, the second magnet having a first pole with a first polarity and a second pole located opposite the first pole and having a second polarity opposite the first polarity, the first rotatable mounting and the non-rotatable mounting positioned within a common plane, such that the first and second poles of the first magnet housed within the rotatable mounting are rotatable within the common plane in which the rotatable mounting and non-rotatable mounting are positioned;wherein, in operation, the second magnet does not move within the non-rotatable mounting in which it is housed. 13. The magnetic latch of claim 12 further comprising a knob assembly attached to the rotatable mounting in which the first magnet is housed. 14. The magnetic latch of claim 13, wherein the knob assembly is attached to the rotatable mounting by a post. 15. The magnetic latch of claim 12, wherein the knob assembly comprises a bushing.
