Abstract: A novel magnetic fastener is realized that utilizes a pair of multipole magnets rotatable relative to each other, allowing the holding force to be selected for ease of operation, namely closing and opening. Each multipole magnet includes a striped pattern of alternating polarity (north and south poles), with the striped patterns having the same pole spacing or pitch. When the stripes of alternating north and south poles are oriented lengthwise, the stripes of the south poles can judiciously align with the stripes of the north poles from the other magnet, creating a strong magnetic force between them to form a fastener. However, when the striped pattern of alternating north and south poles are oriented substantially orthogonal, the stripes are mutually being alternating attracted and repelled, allowing the magnets to be easily separated to effect opening.
