Analysis of Electromagnetic Field Using FEM: A Review

Rishi Sarup Sharma


Before designing any electrical device or apparatus, it is imperative to ascertain the eddy current losses that would occur as per a given design specification. Pre-determining the losses before the design, would expedite the design process besides making it easier to implement the post corrections in the design criteria. The numerical technique harnessed here is the finite element method, which has been used to compute the eddy current losses in different magnetic structures. This method is gaining grounds these days, with the advancement in the technological scenario, witnessed so far. It has been able to fruitfully address the problems encountered in the arena of eddy currents. The bottlenecks or discrepancies experienced in the earlier methods have been eradicated by harnessing the power of this numerical approach. Using the tools of FEM, one can expect higher levels of accuracy and easier set up of design model. It incorporates the complex boundary constraints with the careful combination of the flexibility and ease of programming in the use of algebraic equations.
