Explorers never credibly substantiate, how their alleged magnetism found or measured it. By the way, there is really no need to search for meteoritic origin of iron, in agricultural land itself there is only due to its natural content in a single hectare and only to a depth of 10 cm contained from 7500 to 10,000 tons. If the agricultural land will be at some point exposed even momentarily at about 30 000 degrees C, and to an electric current sometimes in excess of five hundred thousand amperes, some remelted particles (reduced) of iron in would be certainly possible found there.
Sa pamamagitan ng paraan, ay talagang hindi na kailangan upang maghanap para sa sa meteoritic pinagmulan ng bakal, sa agrikultura lupa mismo mayroon lamang dahil sa natural na nilalaman sa isang solong ektaryang at lamang sa isang depth ng 10 cm ang nilalaman mula sa 7,500 sa 10,000 tonelada.
