THEORY OF MAGNETISM
The Magnet Almost everyone has witnessed the effects of magnetism, and many have owned simple permanent magnets such as that illustrated in Fig. 1-13. However, few people realize the importance of magnetism and its relationship to electricity. In the scientific community it is commonly thought that electricity would not exist without magnetism. A magnet may be defined as an object that attracts ferrous metals such as iron or steel. It produces a magnetic field external to itself that reacts with magnetic substances.
