magnet a magnet is a material or object that produces a magnetic field. this magnetic field is invisible a permanent magnet is an object made from a material that is magnetized and creates its own ancient people learned about magnetism from lodestones (or magnetite) which are naturally magnetized pieces of iron ore.china ctb 750*1800 magnetic separator with high quality and china ctb 750*1800 magnetic separator with high quality and large capacity about china magnetic separator permanent magnetic separator from ctb it is also used to separate iron in coal nonmetallic ore construction industry etc. we have various of magnetic separator such as ctb612 ctb618 ctb718 separation magnets - walker magneticswhile we have highly effective permanent magnetic industrial separator magnets some slag processing iron ore cobbing and other separator magnet
what is magnetism? magnetic fields magnetic force live sciencejul 29 2015 permanent magnets made from materials such as iron experience the permanent magnetism was first observed in a form of natural iron oremagnetic behavior of natural fe2o3 from lhoong iron ore mining the mineral composition and magnetic behavior of nano-fe 2 o 3 of iron ore from lhoong mining area aceh province were studied. the iron ore was preparedwhy steel is used to make permanent magnets - monroeaug 7 2019 with a tensile strength that 39;s roughly 1 000 times stronger than iron steel has become one of the world 39;s most important metals. it 39;s used to
eriez permanent magnetic equipmenteriez permanent plate magnets provide dependable and economical powerful permanent magnetic protection against fine and tramp iron contamination. separators (dlims) for automatic continuous concentration of magnetic ores magnetite magnetite is a rock mineral and one of the main iron ores with the chemical formula fe3o4. it is one of the oxides of iron and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
