MAGNETISM. Magnetism. Magnetism is a result of electrons spinning on their own axis around the nucleus (Figure 18). Basic Electrical Theory
Basic Electrical Theory Certain metals and metallic oxides have the ability to attract other metals. This property is called magnetism, and the materials which have this property are called magnets. Some
