Magnetite Lodestone Mineral Photos Uses Properties

The mode softening in magnetite at low temperature appears to result from a bilinear coupling of the elastic strain to a charge ordering process between Fe 2 and Fe 3 on the octahedral site as is observed in analog compounds Schwenk et al 2000 Paolone et al 2003 but it is unlikely that increasing pressure would drive such charge

How Magnets Work HowStuffWorks

But the physical process that magnetizes compass needles and chunks of neodymium alloy is essentially the same It relies on microscopic regions known as magnetic domains which are part of the physical structure of ferromagnetic materials like iron cobalt and nickel Each domain is essentially a tiny self contained magnet with a north and
