在相对论电动力学中相对性原理的有效性探讨

揭示了相对论电动力学中存在的矛盾。对于一个在S参照系中静止的电偶极子,在与S参照系相对运动的S'参照系中进行受力分析时,得到了与S参照系全完不同的结果,引发了一个严重的谬误。研究表明,一些电磁学定律在络伦兹变换下并不满足相对性原理的要求。

Mutual Inductance Calculation Between Arbitrarily Positioned Polygonal Coils

Polygonal coil systems are designed for increasing and more kinds of sensors and electromagnetic systems.This paper presents a method for calculating mutual inductance between polygonal coils including irregular polygons.Based on the Biot-Savart law,the method calculates mutual inductance by dividing a polygonal coil into finite wires,and expresses the magnetic induction intensity generated by the excitation coil as a function of the spatial position of each vertex of the coil.The calculation method of the feasible region of the objective function is updated and the calculation process is simplified,so the calculation accuracy is improved.For octagon coils arbitrarily positioned in space,the accuracy of the algorithm is verified by the simulation and experiment.
