Two-dimensional magnetostriction under vector magnetic characteristic

“…We developed a new measurement method for measuring the vector magnetic characteristic and twodimensional magnetostriction of the electrical steel sheet. [4][5][6][7][8] In the new measurement method, it is possible to evaluate an angle (h BH ) between the magnetic flux density vector and the magnetic field strength vector, and an angle (h Bk ) between the magnetic flux density vector and the direction of maximum magnetostriction, as shown in Fig. 1.…”
