Abstract: The present invention provides a simple magnetic hinge using a magnet placed in a moveable object to attract a metal piece disposed in a fixed object on the other side; both of the objects are assembled into an unit by a rivet; when the external force exerted on the movable object is greater than the magnetic force of the magnet for attracting the metal piece, these two objects are separated to hinge or move; when the external force exerted on the movable object disappears, these two objects stay at their original positions, tightly joint together and can't be separated.
