为了提高测量精度，采用有限元方法对旋转磁通条件下用磁场感应线圈（H线圈）测定电工钢磁性能的装置中的磁场和损耗进行了数值分析。这里考虑的方法是基于场量的确定，并利用方形样品和极面与样品之间的气隙。采用优化的轭架结构和双h圈法减小了场强和损耗的误差。
The magnetic field and loss in an apparatus for the determination of magnetic properties of electrical steel under rotational flux conditions using field sensing coils (H coils) is numerically analyzed by finite element calculations in order to improve accuracy. The method considered here is based on determination of field quantities and makes use of square-shaped samples and an airgap between the pole faces and the sample. Errors in field strength and loss are reduced by using optimum yoke construction and the double H-coil method.
