Rotational magnetic loss in magnetic core materials has been examined on the direction of rotation at high magnetic flux density. Rotational losses differ remarkably over 1.5T in accordance to the decrease of phase difference between magnetic field H and magnetic flux density B. The rotational losses in clockwise or anticlockwise directions depend largely on inclination angle of magnetic filed sensing axis to orthogonal magnetic flux axes. A reasonable correction of the rotational losses is proposed by measured losses in practical measurements.
