Magnetic Properties

Natural Science and Advanced Technology Education, 2022
Magnetism is one of the earliest of the physical phenomena and materials characteristics observed in nature and subjected to scientific study. The dramatic effect of the attraction of iron by lodestone (primarily magnetite, Fe3O4 with inclusions of maghemite, cubic Fe2O3) is perhaps the historic beginning of magnetism.
