MAGNETICS TUTORIAL. MODELING PERMANENT MAGNETS USING THE ELECTROMAGNETIC SOFTWARE FEMM 4.2

Abstract

We live in an era characterized by an informational explosion, of an accelerated and revolutionary technical progress, and it is, therefore highly important to ask questions, to evaluate risks, to change methodologies, concepts and to create new learning situation, making use of the creative potential of our students. We need to rethink how we communicate while teaching, we should emphasise a collaborative process where different pieces of opinion and perspectives are taken into consideration. Teaching and learning by means of information and communication technologies as well as new educational software in the domain of mathematics or engineering (solutions offered by software in e-learning require a complex teaching-learning system via laptops, smart phones, tablets, e-learning platforms, internet) support a collaborative process, and promote skills of paramount importance in the context of 21st century. Today, learning means knowing to search and deal with recent information, to exchange ideas on specialized forums, on e-learning platforms in order to actively contribute to the improvement of the already existing educational data. This can sometimes be done via especially designed questionnaires. Learning and teaching should nowadays rely on modern technologies. This is one of the subjects to be tackled in this article. Students should have access on e-learning platforms using individual account, while teachers should be aware of how these technologies work. The on-line environment should be continuously updated and improved so that those participants attending a course would feel motivated. What I more, the article deals in both a theoretical and experimental way with an important subject in electromagnetism, the permanent magnets. Starting off from knowledge known in the specialized literature and practice, what we propose is a tutorial to model permanent magnets, using FEMM.  4.2. software.
