Question

What is the numerical methods in electromagnetic fields?

Answer 1

Finite element method (FEM) is one of the most successful numerical methods for solving electrostatic field problems. FEM can be employed successfully for the computation of an electric field between electrodes in a medium where one or more dielectrics are involved.

Answer 2

An electromagnetic field is a classical field produced by moving electric charges. It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics
