PROBLEM TO BE SOLVED: To provide a (precise orientation) measure that can make all the orientation directions ofχ<SB>1</SB>,χ<SB>2</SB>, andχ<SB>3</SB>similarly concerning each material object composing an aggregate of different material objects, whose magnetic susceptibilitiesχ<SB>1</SB>,χ<SB>2</SB>, andχ<SB>3</SB>toward three directions are different, especially to provide a measure that is even useful for precise orientation of a system that is composed of small particles and is easily disturbed by thermal agitation, hence whose orientation by a usual orientation technology using magnetic field is difficult. SOLUTION: The method for producing precisely oriented material using magnetic field comprises orienting precisely the three magnetic susceptibilitiesχ<SB>1</SB>,χ<SB>2</SB>, andχ<SB>3</SB>of a material object by impressing an aggregate of material objects, whose three magnetic susceptibilitiesχ<SB>1</SB>,χ<SB>2</SB>, andχ<SB>3</SB>are different, with a magnetic field (a high-speed rotating elliptic magnetic field) rotating elliptically with a larger angular velocityωthan the inverse of an orienting timeτunder a static magnetic field.
