Magnetic Materials. The term magnetism is derived from Magnesia, the name of a region in Asia Minor where lodestone, a naturally magnetic iron ore, was found in ancient times. Iron is not the only material that is easily magnetized when placed in a magnetic field; others include nickel and cobalt. Carbon steel was long the material commonly ...

The copper and cobalt ores are found in a 500-million-year-old mountain chain in two zones, weathered oxide deposits that extend to a depth between 70 m and 150 m and unweathered sulfide deposits below these oxide deposits at depths greater than 250 m. The weathered part of the deposit is easily mined by surface scrapers, bulldozers and diggers.
