PROBLEM TO BE SOLVED: To establish the magnetic field analysis method of two-dimensional vector magnetic characteristics considering stress characteristics. SOLUTION: A database 101 is created by using a two-dimensional magnetism measuring apparatus for measuring two-dimensional vector magnetic characteristics under excitation conditions with stress characteristics (stressσand an inclination angleθ<SB>B</SB>σfrom the axes of easy magnetization of stress) as one of parameters, measuring the two-dimensional vector magnetic characteristics of each kind of magnetic material in each excitation condition, and databasing the result. A magnetic field analyzer 102 utilizes the databased result in the database 101, analyzes a magnetic field by the finite element method of an analysis target using the modelling (for example, E&S modelling) of two-dimensional vector magnetic characteristics for expressing the relationship between magnetic flux density and magnetic field strength, and obtains magnetic field strength, iron loss, or the like in the analysis target.
