METHOD OF ESTIMATING THE CLOSED-CIRCUIT PROPERTIES OF A MAGNETIC MATERIAL

An improved method for estimating the characteristic properties of a magnetic material as if they were measured in a closed-circuit environment. The method utilizes open-circuit measurements obtainedusing a pulsed field magnetometer and a computer model of the magnetic body. An iterative method is used which allows the calculation of an accurate closed-circuit characteristic. The method is more general than previous solutions, being applicable to any three-dimensional volume. Greater accuracy is achieved by reducing the need for approximations and guesswork. 一种用于如同它们在闭路环境中被测量的那样来估计磁性材料特性性质的改进方法。该方法利用使用脉冲磁场磁强计和磁性主体的计算机模型获得的开路测量。使用允许计算精确的闭路特性的迭代方法。该方法比之前的方案更通用，适用于任何三维体积。通过减少对近似和猜测的需要，可以实现更高的精度。
