Fundamental Principles of Magnetic Inductionbe covered in this chapter start with a brief history of magnetism and how magnetism is linked with electricity. The study of linking electricity and magnetism further leads to a discussion of how magnetic fields are produced due to an electric current and how a time-varying magnetic field induces a
