Orbital And Spin Effects for Learning the Classification of Magnetic Materials in Engineering Electromagnetics |Biomedgrid

Magnetics is usually harder to learn than electrostatics. This statement is true not only for students but also for most engineers and scientists [1,2]. The reason is that most properties in electrostatics are linear and use inner products, but most properties in magnetics are curves and employ outer products. Therefore, electrostatics is intuitive, but magnetics is abstract. Another possible reason is associated with the curriculum design regarding instruction on electromagnetics. Most textbooks and courses related to electromagnetics are arranged to begin with electrostatics, which includes the basic and easy topics that most educators consider readily teachable. Typically, the students who are taking the course do not absorb electrostatics completely, and then they suffer as they fail to learn magnetics. Thus, students must prepare more before learning magnetics. In fact, most educators might agree that electromagnetics has a steep learning curve.
