According to structure features, parallel plane field and axisymmetrical field were used in approximate calculations of core and yoke of the valve respectively.
根据电磁阀的结构特点，将磁芯和磁轭分别按平行平面场和轴对称场近似处理。

This method may possibly be used to estimate influence of high order harmonic field on hysteresis loss to optimize the design of deflection yoke ring and to develop energy saving ferrite materials.
The lifting power of the yoke was not relative to the magnetic field composed in the workpiece tested, so it could not reflect the magnetizing power of the yoke.
