A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components within the proposed geometry. Furthermore, based on the structure configuration, students can use obtained magnetic flux density components to define the appropriate normal component relative to any selected closed surfaces. Consequently, by simple and direct boundary integration, students will immediately get access to accurate values of flux linking and mutual inductance, even for complex geometries, where mathematical calculation becomes prohibitive.
