Abstract

This paper presents data on the modeling of an electromagnet for the finishing equipment, which provides flexible and effective work. The modeling was performed by using Finite Element Method Magnetics (FEMM) software intended for solving 2D planar and axisymmetric problems in low frequency magnetics. The modeling data demonstrates the best shape, shape-and-size-ratio of electromagnet, which would ensure maximum efficiency when using the aforementioned device. An electromagnetic field generator, consisting of four electromagnets, was constructed. Subsequently it was determined that generated magnetic field was far smaller than in the model
