Many natural substances in nature exhibit magnetism, which has a significant impact on human life. However, accurately predicting, analyzing, and manipulating magnetic fields requires the use of precise mathematical simulation techniques. One such method is numerical modeling with element matrices, crucial for simulating analyzing complex physical models. In conventional mesh-based modeling, there always residual error, accuracy solution can be greatly affected by mesh density. This work proposed new theory field magnetics, based specially designed points within an element. With this computational framework, mesh-dependence feature matrix significantly reduced, allowing more efficient convergence to theoretical value minimal differences. handle wide range extreme conditions both three-dimensional two-dimensional scenarios, are beyond capabilities methods, provide highly accurate solutions. The demonstrated through passive shielding design 9.4 T whole-body resonance imaging superconducting magnet, concept extremely weak scientific facility cross-scale geometry was exemplified method.
