Joystick assembly
A joystick assembly for use with a device including a joystick surface and a first magnet having north and south magnetic poles includes a second magnet having north and south magnetic poles and a movable elongated shaft having first and second opposing ends arranged along a major axis of the shaft. The first end of the shaft is coupled to the second magnet such that movement of the shaft results in movement of the second magnet relative to the first magnet such that a line between centers of the north and south magnetic poles of the second magnet is movable relative to a line between the north and south magnetic poles of the first magnet. An attraction of the second magnet to the first magnet results in a restoring force upon the shaft, and the shaft and the second magnet are removable from the joystick surface.

8. The joystick assembly of claim 1 , further comprising a hinge coupled between the moveable elongated shaft and the handle so that the handle is pivotable about at least one axis with respect to the moveable elongated shaft.
9. A joystick assembly for use with a device comprising a first magnet having north and south magnetic poles, comprising:
a second magnet having north and south magnetic poles;
a movable elongated shaft having first and second opposing ends arranged along a major axis of the shaft, the first end fixedly coupled to the second magnet such that movement of the shaft results in movement of the second magnet relative to the first magnet such that a line between centers of the north and south magnetic poles of the second magnet is movable relative to a line between the north and south magnetic poles of the first magnet, wherein an attraction of the second magnet to the first magnet results in a restoring force upon the shaft; and
a handle coupled proximate to the second end of the movable elongated shaft, wherein the handle is foldable with respect to the shaft,
wherein the movable elongated shaft comprises at least an inner tube and an outer tube which is telescopically slideable with respect to the inner tube.
10. The joystick assembly of claim 9 , wherein the moveable elongated shaft is configured to extend from a first distance to a second distance, said second distance greater than the first.
11. The joystick assembly of claim 9 , wherein the moveable elongated shaft is configured as at least one of a stylus or pointing device operable with the device.
12. The joystick assembly of claim 11 , wherein the device is at least one of a smartphone, a tablet computer, an instrumentation console, a video game console, a video game controller, a keyboard, and a laptop computer.
13. The joystick assembly of claim 9 , further comprising a hinge coupled proximately between the second end of moveable elongated shaft and the handle so that the handle is pivotable about at least one axis with respect to the moveable elongated shaft.
14. A joystick assembly for use with a device comprising a first magnet having north and south magnetic poles, comprising:
a second magnet having north and south magnetic poles;
a movable elongated shaft having first and second opposing ends arranged along a major axis of the shaft, the first end fixedly coupled to the second magnet such that movement of the shaft results in movement of the second magnet relative to the first magnet such that a line between centers of the north and south magnetic poles of the second magnet is movable relative to a line between the north and south magnetic poles of the first magnet, wherein an attraction of the second magnet to the first magnet results in a restoring force upon the shaft; and
