1. A portable magnetic closure apparatus, comprising:

  • a first housing member having a computer and a first single layer magnetic member;

    a second housing member;

    a sliding member slidable with respect to the second housing member;

    a magnetic apparatus with a dual layer magnetic member linked to the sliding member, wherein said sliding member is slidable from;

    a. a latching position in which a magnetic pole in said first single layer magnetic member faces an opposite-polarity magnetic pole in said dual layer magnetic member to cause attraction between said opposite-polarity magnetic poles and thereby latch said second housing member to said first housing member, to b. an unlatching position in which a magnetic pole in said first single layer magnetic member faces a like-polarity magnetic pole in said dual layer magnetic member to cause repulsion between said like-polarity magnetic poles and thereby facilitate unlatching of said first and second housing members.
