Abstract

Modeling of magnetodynamic problems always exists and plays an important role in the fields of electrical systems in general and electrical equipments in particular. It can be considered as a spine problems decided to the working process of the electrical systems and devices.  Hence, the analysis, computation and simulation of physic phenomena, electromagnetic processes of the magnetodynamic problems is really an important topic concerning for researchers in Viet Nam and in the world as well. In this study, a magnetic vector potential formulation is developed by one way-coupling subproblem technique  to calculate field quantities (magnetic field density, eddy current density, joule power loss) existing and occuring in the thin shell structures neglecting edge and corner effects. The development of the method will be verified to be applied to the real problem “TEAM problem 21, model B).
