Kód produktu D x H Kvalita Povlak Prídržná sila Dostupnosť Cena; 35.001-N45: 1.5 x 3 mm: N45: Ni: 0.6 N: Skladom: 0,08 € Dysprosium (Dy) or terbium (Tb) is added to curb the fall in performance from temperature changes, making the magnet even more expensive. [23], Neodymium has a negative coefficient, meaning the coercivity along with the magnetic energy density (BHmax) decreases with temperature. For sintered NdFeB magnets, there is a widely recognized international classification. Neodijumski Magneti / Neodym magnet, Novi Beograd. The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Sintered Nd-magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. Sehr teuer für die kleine Magnete. Also this could be a serious health risk if working with machines that have magnets in or attached to them [26] The stronger magnetic fields can be hazardous to mechanical and electronic devices, as they can erase magnetic media such as floppy disks and credit cards, and magnetize watches and the shadow masks of CRT type monitors at a greater distance than other types of magnet. Anunturi pe OLX.ro Adauga anunt nou. In some cases, chipped magnets can act as a fire hazard as they come together, sending sparks flying as if it were a lighter flint, because some neodymium magnets contain ferrocerium. [38], Neodymium magnets are used as a surgically placed anti-reflux system which is a band of magnets[39] surgically implanted around the lower esophageal sphincter to treat gastroesophageal reflux disease (GERD).

Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a ferrous metal surface, even causing broken bones.[25]. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spalling of a surface layer. The blocks are then heat-treated, cut to shape, surface treated and magnetized. View basket for details.

[30] China produces more than 95% of rare earth elements and produces about 76% of the world's total rare-earth magnets, as well as most of the world's neodymium.[31][9]. Some important properties used to compare permanent magnets are: Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types of magnets.
