Abstract��According to the principle of ballistic method in direct current magnetic measurement, the ballistic constant C�� should be accurately calibrated before measuring magnetic induction intensity B. There are many factors which influence the exact measurement of C��. C�� is obtained by orthogonal test method and the C�� is calibrated using a standard sample. Finally, the high precise measurement of saturation induction density Bs is obtained.
