FERROMAGNETIC THIN PLATE COMPOSITE DOUBLE SIDE MAGNET SHEET AND MAGNETISM DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polygonal magnetism display piece and a magnetism display device in which magnetic attraction is enhanced.;SOLUTION: In a ferromagnetic thin plate composite both side magnet sheet 20 where a flexible magnet layer subjected to multipolar magnetization is formed on both sides of a ferromagnetic thin plate 1, a magnetic closed circuit is formed of a magnet layer held by the attracted body to a ferromagnetic material and the ferromagnetic thin plate 1, when the attracted body to a ferromagnetic material is attracted magnetically, and thereby a magnetic attraction force much stronger than that of a single side multipolar magnetization can be obtained on both sides. Furthermore, a magnetic attraction force equivalent to that of a single side magnetization sheet can be obtained using a both-sided magnet sheet 22, and 2-4 sides can be used while re-pasting depending on the intended purpose, by giving a printable layer on both sides.;COPYRIGHT: (C)2015,JPO&INPIT
