Abstract
The magnetic properties of silicon steel sheet under the condition of two-dimensional excitation (circular, elliptic and alternating with rotation of the direction) are investigated. Two-dimensional magnetic measurement is a generic term introduced recently to comprise the measurement of magnetic properties of a specimen under the condition of rotating magnetic induction. Two-magnetic properties in silicon steel sheet are very sensitive to the axis ratio and the inclination angle of the magnetic flux density of longitudinal axis,because that is very effective to the anisotropy of the sheet.
