e test coil is to be multiplied by two in each case to give the truechange in induction. The value of the induction at any point on the loop is theinduction at the tip minus the chtmge in induction. Points at the left of the OBaxis are obtained by reversing the direction of the magnetizing force at… … Fig. 16.—Typical hysteresis loop In practice the tip of the loop is set either at a definite induction or at the inductioncorresponding to a definite magnetizing force. Switches SM, SC^-SM\ and SC areclosed downward and compensation effected for the required tip as in j. R^C^^r isincreased to…
