Electrical steel sheets have been widely employed as a magnetic core material of an electromagnetic equipment. Magnetic materials in the equipment is possible to be excited by two-dimensional AC-magnetization and/or ACmagnetization with two-dimensional DC-biased magnetization. In this paper, the magnetic properties of electrical steel sheets under two-dimensional DC-biased magnetization have been researched. The phase difference of between the fundamental components of B and H under high
