 There are numerous types of magnetic behaviour, many of them being highly [[non-linear]]. For instance [[ferromagnetism]][([[http://books.google.com/books?isbn=0780310322|Bozorth R.M., Ferromagnetism, IEEE Press, John Wiley & Sons, New York, 2003, ISBN 0-7803-1032-2]])] continues to have a major impact on the evolution of various technologies, mainly through its involvement in energy generation and conversion. Most of the electricity generated worldwide is converted, transmitted and consumed with the use of ferromagnetic and electromagnetic phenomena.  There are numerous types of magnetic behaviour, many of them being highly [[non-linear]].
