Basic Electrical Theory MAGNETISMMAGNETISMCertain metals and metallic oxides have the ability to attract other metals. Thisproperty is called magnetism, and the materials which have this property arecalled magnets. Some magnets are found naturally while others must bemanufactured.EO 1.6 DEFINE the following terms:a. Magnetic fluxb. Magnetic flux densityc. Weberd. Permeabilitye. Magnetomotive force (mmf)f. Ampere turnsg. Field intensityh. ReluctanceEO 1.7 DESCRIBE the following materials as they relate topermeability, including an example and an approximate relativepermeablity.a. Ferromagnetic materialsb. Paramagnetic materialsc. Diamagnetic materialsMagnetismMagnetism is a result of electrons spinning on their own axis around the nucleus (Figure 18).Figure 18 Electron Spinning Around NucleusProduces Magnetic FieldRev. 0 Page 27 ES-01
