PROBLEM TO BE SOLVED: To provide a magnetizing coating material mixture, capable of effectively and inexpensively preventing rusting after coating even in a water-soluble magnetizing coating material, and a magnetizing coating material.SOLUTION: A mixture of iron powder and at least one metal powder larger in ionization tendency than iron is used as a raw material of a magnetizing coating material. Zinc powder which is easily dissolved even in water is most effectively adopted, and the weight ratio of the mixed metal powder to the iron is 3-20%, or the area of the iron powder is 6-9 times the area of the metal powder. |
