The primary incontestable reference to the "magnetized needle" in Chinese literature seems in 1088.[36] The Desire Pool Essays, penned via the Music dynasty polymath scientist Shen Kuo, contained an in depth description of how geomancers magnetized a needle by rubbing its idea with lodestone and hung the magnetic needle with one particular solitary pressure of silk with some wax connected to the center in the needle. Shen Kuo pointed out that a needle organized this way sometimes pointed south, often north.
