Abstract
A particle comprising a magnetic particle is placed in a liquid having a monomolecular film formed on its surface. Then, the particle is pulled up by means of a pair of electromagets facing each other with the air-liquid interface present therebetween so that the particle passes through the interface. As a result, a monomolecular coat is formed on the surface of the particle. A monomolecular built-up coat is formed by repeating the above procedure predetermined times.
