Abstract: A magnetic sheet comprising permanent magnetic particles arranged in a pattern to form alternating elongated zones of first and second opposite polarities, each zone being defined by spaced apart parallel zigzag boundary lines formed by a plurality of equal length, substantially linear segments which meet at point contacts to form sharp turns, with angles formed at the sharp turns and defined by connected segments being 90/, each zone of the first polarity being bounded by only two zones of the second polarity positioned on opposite sides thereof, and each zone of the second polarity being bounded by only two zones of the first polarity positioned on opposite sides thereof. The magnetic sheet of the invention has many applications, including a removable insole for insertion into footwear.
