One of the earliest known references to lodestone's magnetic properties was made by 6th century BC Greek philosopher [[Thales of Miletus]],<ref>{{cite web | last = Brand | first = Mike | author2 = Sharon Neaves | author3 = Emily Smith | title = Lodestone | work = Museum of Electricity and Magnetism, Mag Lab U | publisher = US National High Magnetic Field Laboratory | year = 1995 | url = http://www.magnet.fsu.edu/education/tutorials/museum/lodestone.html | access-date = 2009-06-21 | archive-url = https://web.archive.org/web/20090501063207/http://www.magnet.fsu.edu/education/tutorials/museum/lodestone.html | archive-date = 2009-05-01 | url-status = dead }}</ref> whom the ancient Greeks credited with discovering lodestone's attraction to iron and other lodestones.<ref>{{cite book | last = Keithley | first = Joseph F. | title = The Story of Electrical and Magnetic Measurements: From 500 B.C. to the 1940s | publisher = John Wiley and Sons | year = 1999 | pages = 2 | url = https://books.google.com/books?id=uwgNAtqSHuQC | isbn = 0-7803-1193-0}}</ref> The name ''[[magnet]]'' may come from lodestones found in [[Magnesia ad Sipylum|Magnesia]], [[Anatolia]].<ref>The [[Ancient Greek|Greek]] term μαγνῆτις λίθος ''magnētis lithos'' (see [https://archive.org/details/bub_gb_BkS2KW7u76MC ''Platonis Opera''], Meyer and Zeller, 1839, p. 989) means "Magnesian stone". It is uncertain whether the adjective μαγνῆτις "of Magnesia" should be taken to refer to the city ''Magnesia ad Sipylum'' in [[Lydia]] (modern-day [[Manisa, Turkey]]) or after the Greek region of [[Magnesia (regional unit)|Magnesia]] itself (whence came the colonist who founded the Lydian city); see, for example, {{cite web|url=http://www.languagehat.com/archives/001914.php |title=Magnet |work=Language Hat blog |date=28 May 2005 |access-date = 22 March 2013}} See also: Paul Hewitt, ''Conceptual Physics''. 10th ed.

The earliest Chinese literary reference to magnetism occurs in the 4th-century BC ''Book of the Devil Valley Master'' (''[[Guiguzi]]'').<ref>The section "Fanying 2" ([[:s:鬼谷子|反應第二]]) of ''The [[Guiguzi]]'': "{{lang|zh|其察言也，不失若磁石之取鍼，舌之取燔骨}}".</ref>
In the chronicle ''[[Lüshi Chunqiu]]'', from the 2nd century BC, it is explicitly stated that "the lodestone makes [[iron]] come or it attracts it."<ref>{{Cite book |title=Encyclopedia of Chinese History |last= Dillon |first= Michael |publisher= Routledge |year=2017 |isbn=978-0415426992 |pages=98}}</ref><ref name=Li54>{{cite journal |last=Li |first=Shu-hua |title=Origine de la Boussole II.
