Title: Material for forming magnetic film
Inventor: WAKIYA MASANORI
IPC: H01F41/16
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To impart a property of being attracted by a magnet to desired positions of an arbitrary material, by mixing a material powder having property to be attracted by the magnet, in an adhesive which is diluted by an alcohol or water-soluble solvent. SOLUTION: A solvent diluted with an alcohol or water-soluble solvent is used. In such a solvent, a solute of powder material having a property attracted by magnetism is mixed by a specified amount to provide a film which is attracted by a magnet. As the solute, stainless steel powder 1, other iron-group alloy, or rare-earth, etc., are used. If a starch paste or a general handicraft bond is used as the solvent, the particle size, etc., of the powder 1 is such that a solute is not easily precipitated in a sol-like solvent, with the viscosity of solvent considered. With this coated on the surface of a desired material, such performance as attracted by a magnet is imparted even if the material is non- magnetic.
