ABSTRACT:
The invention is a magnetic coupling device that utilizes a supported spherical magnet to attach to a hole in a ferromagnetic object. The hole shape and the orientation of the spherical magnet are predetermined to form a relatively strong magnetic attachment. The magnetic coupling device exhibits unique characteristics such as angular tolerance, precise positioning and controllable release characteristics.
