| contents | Mexico and the early history of magnetism A. P. Guimaraes Física, Astronomía y Matemáticas Olmecs Mexico Magnetism The phenomenon of magnetism has been known by mankind for more than three thousand years. This fact is documented in references tothe naturally occurring magnetic mineral magnetite (the iron oxide Fe3O4) in clay tablets in ancient Mesopotamia, as early as the secondmillennium BC. Less known, however, is the possible evidence for the knowledge of the magnetic properties of rocks by the peoples ofpre-Columbian America. In fact, archaeologists have found in Olmec sites in Mexico many objects made of iron ore that may reveal an earlyacquaintance with magnetism. The Olmecs constituted the first complex culture that appeared in the Americas, before 1000 BC, in the eastcoast of Mexico. Among these objects, there has been found a polished bar that is magnetic, dating from 1400-1000 BC, which has led tospeculations that it may have been part of a magnetic compass, one thousand years before the first Chinese compasses were made. 2004 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063107 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
