Abstract

PURPOSE:To obtain a powerful attracting force without deterioration thereof by sticking soft magnetic powder and permanent magnetic powder on flexible tape- shaped bodies and vertically magnetizing the surfaces to form multipoles. CONSTITUTION:Soft magnetic powder 2 and permanent magnetic powder 3 in which binders 4 and 4' is mixed are applied on flexible tapes 1. Then, the binder is cured, with the surfaces of said tapes A and B being vertically magnetized to form multipoles. Since the attracting forces of these tapes A and B are proportional to the amount of magnetization, the attracting forces become proportional to N<2> when both tapes are divided into N portions which are to be magnetized. Since the soft-powder layers 2 serve as a magnetic yoke locate at the back surfaces where the multipole magnetization is performed, the attracting forces are multiplied. As these tapes utilize the attracting forces of the magnets, the attracting forces of the tapes used for the attracting portions which are frequently loaded and unloaded are not deteriorated and are very effective.
