电场力、磁场力两种计算方法的讨论

The Analysis of Two Calculation Methods for Electric Force and Magnetic Force

应用两种方法讨论了电、磁场力的计算问题。第一种方法从Maxwell方程出发 ,建立场的动力学方程 ,引入电磁场张力张量及应力关系 ,从而计算电、磁场的应力 ;第二种方法从电、磁场力的公式及场的叠加原理出发 ,计算电、磁场力。

This paper discusses two calculation methods for electric force and magnetic force.First,in accordance with Maxwell equation,dynamical equation of field is set up.By the relations of tensile force,tensor and stress on electric field and magnetic field,the stress on electric field and magnetic field is calculated.Second,with the formula of electric force,magnetic force and field superposition theorem,the other calculation is put forword for electric force and magnetic force.
