Abstract: The coercivity of soft magnetic materials is generally near to zero point． On the first hand， in the conditions of near-zero applied field， the results of measurement are often coupled by noise； on the other hand， compared to maximum applied field for saturation magnetization， the resolution of the coercivity of soft magnetic materials becomes low． The paper presents a method of delay extrapolation for high-resolution estimation of the coercivity．
