Lodestones are naturally magnetized pieces of the mineral magnetite. [ 1 ] [ 2 ] They are naturally occurring magnets , which can attract iron . The property of magnetism was first discovered in antiquity through lodestones. [ 3 ]
Lodestones were used as an early form of magnetic compass. Magnetite has been a critical tool in paleomagnetism , a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields .
Ancient people learned about magnetism from lodestones (or magnetite) which are naturally magnetized pieces of iron ore.The word magnet was adopted in Middle English from Latin magnetum "lodestone", ultimately from Greek μαγνῆτις [λίθος] (magnētis [lithos]) [1] meaning "[stone] from Magnesia", [2] a place in Anatolia where lodestones were found (today Manisa in modern-day Turkey).
The first recorded appearance of the use of the compass in Europe (1190) [23] is earlier than in the Muslim world (1232), [24] [25] as a description of a magnetized needle and its use among sailors occurs in Alexander Neckam's De naturis rerum (On the Natures of Things), written in 1190. [23] [26] However, there are questions over diffusion.
Using observations of neutron scattering, the magnetic moments were shown to align into interwoven tubelike bundles resembling Dirac strings. At the defect formed by the end of each tube, the magnetic field looks like that of a monopole. Using an applied magnetic field to break the symmetry of the system, the researchers were able to control ...
