This paper discusses how to accurately determine and use the magnetic properties of materials such as electrical steels. The "vector magnetic property" means the relationship between the vector of the magnetic flux density B and the vector of the magnetic field strength H. Therefore the vector magnetic property for the H and B vectors has non-linearity not only in its amplitude but also in its phase difference angle on the H vector and the B vector. In order to express the relation, I have proposed an engineering model called the "E & S model," which can be introduced into numerical simulation techniques such as the finite element method. This method is useful for the development of high-efficiency electrical machines using the highquality electrical steel sheets. In the second part of the paper, the behavior of magnetostriction is investigated from the vectorical viewpoint.
