Magnetic Properties of Materials
Modern technology would be unthinkable without magnetic materials and magnetic phenomena. Magnetic tapes or disks (for computers, video recorders, etc.) motors, generators, telephones, transformers, permanent magnets, electromagnets, loudspeakers, and magnetic strips on credit cards are only a few examples of their applications. To a certain degree, magnetism and electric phenomena can be considered to be siblings since many common mechanisms exist such as dipoles, attraction, repulsion, spontaneous or forced alignment of dipoles, field lines, field strengths, etc. Thus, the governing equations often have the same form. Actually, electrical and magnetic phenomena are linked by the famous Maxwell equations, which were mentioned already in Chapter 10.
