<p>A very thin magnetic attachment which exhibits a sufficiently strong magnetic attraction. The magnetic attachment is composed of, for example, a plurality of permanent magnets (11-14) which have attracting bottom faces (4) and are arranged at intervals, a soft magnetic material (21) which covers the side faces of the magnets (11-14) and forms a plate-like shape together with the magnets (11-14), and top-face covering member (3) which covers the top faces of the magnet (11-14) and is made of a soft magnetic material. The attracting bottom faces (4) of the magnets (11-14) are magnetized to have the same pole, N pole or S pole. A plurality of loops of magnetic lines of force are formed from each magnet (11-14).</p> |
