Abstract :
Magnetic coupling occurs when magnetic field lines of an electrical circuit are closing into another electrical circuit. This can be an undesired effect that affects both circuits.The coupling element is mutual inductance. This paper aims to analyze the effects of inductive coupling determined by the variation of a disturbing electric current. Coupling capacity or mutual inductance between three circuits will be determined by solving the electromagnetic field issue. Reducing the effects of the inductive coupling will be simulated in COMSOL AC power Electromagnetics, by placing a ferromagnetic material between the disturbing circuit and the perturbed circuits at different distances.
