A magnetic latch includes a first member (301) having a protrusion and a second member (305) engaging the protrusion prevent the first member (301) and the second memb er (305) from sliding relatively to one another. The second member includes a first magnet (230) to attract the first member (301) and a first solid non - magnetic member (319a) located inside a cavity of the first magnet (230) to enhance attraction between the first member (301) and the second member (305), The second member (305) can be provided with a backing plate (315a) to facilitate a magnetic flux pa th from the magnet to the magnet aperture. The second member (305) can also include a second magent to attract the first member (301) and a second solid non-magnetic member locat- ed between the first magnet (230) and the second magnet. A third solid non- magnetic member can be provided on the outer peri- phery of the magnets. This design provides a latch with stronger holding power,
