Technical Examples
  1. A jewelry clasp with top and bottom sections, each section having a bore to receive a magnet, and each section having an interlocking surface on the perimeter of the bore. An eyelet is positioned on the perimeter of each section. The interlocking surfaces consist of mating camber protrusions that will lift and separate the top and bottom sections when the sections are rotated in one direction by the eyelets. One magnet is longer than the other to provide structural resistance to separation at the camber protrusions by opposing force exerted through the eyelets. In another embodiment, a steel tube is positioned in the bore of one section to encase the magnets to redirect magnetic flux and provide additional structural resistance against opposing force through the eyelets. Additional steel shielding can be used to reduce magnetic flux emanating from the clasp. Neodymium magnets coated with gold or silver are preferred.
