188–190p. Abstract: Although magnetic materials had been studied for over 2000 years, it was not until the development of quantum mechanics in the early years of the 20th century that any satisfactory explanation of their properties could be provided. This paper outlines some of the difficulties that this fact presents for teachers attempting to explain permanent magnetism to learners at different levels who do not have a background in quantum physics. The authors suggest how a consistent and physically correct approach may be achieved. ***______{For Hard Copy, Please visit Library.}________*** Magnetic properties| Ferromagnetism| Magnetic materials| Magnetic dipole moment| Classical electromagnetism| Spin angular momentum 0031-921X https://doi.org/10.1119/5.0120835 https://doi.org/10.1119/5.0120835 240508 20240508095606.0
