Magnets that get too near each other can strike each other with enough force to chip and shatter the brittle magnets, and the flying chips can cause various injuries, especially eye injuries. Their values range from 28 up to 52. Special neodymium magnet alloys that include terbium and dysprosium have been developed that have higher Curie temperature, allowing them to tolerate higher temperatures. Neodymium-iron-boron magnets have high coercivity at room temperature, but as the temperature rises above 100 °C (212 °F), the coercivity decreases drastically until the Curie temperature (around 320 °C or 608 °F). [37], The strength and magnetic field homogeneity on neodymium magnets has also opened new applications in the medical field with the introduction of open magnetic resonance imaging (MRI) scanners used to image the body in radiology departments as an alternative to superconducting magnets that use a coil of superconducting wire to produce the magnetic field. Ein Neodym-Magnet hält bis zum 2000-fachen des Eigengewichtes. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals, or polymer and lacquer protective coatings, are also in use. Sehr teuer für die kleine Magnete. Oe). Most importantly, it is said to be possible to control a non-uniform orientation of the magnetic field in the sintered material to locally concentrate the field to, e.g., improve the performance of electric motors. Wir haben diesen Neodym Magneten bisher ausschließlich in der Güte N45 angeboten, jetzt gibt es auch eine günstigere Version in N40.. Neodym Scheiben Magnet 20x10mm, N40, Ni-Cu-Ni The name of the rare earths is not due to their concentration in nature but to the difficulty which occurs in the separation of these from other materials with which they are linked through chemical bonds.

Neodijumski Magneti / Neodym magnet, Novi Beograd. This fall in coercivity limits the efficiency of the magnet under high-temperature conditions such as in wind turbines, hybrid motors, etc. Neodymium magnets can be found on the market with the name of magnets neodymium iron boron, or NdFeB magnets. This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. The method exploits an "organic/inorganic hybrid technology" to form a clay-like mixture that can be fashioned into various shapes for sintering. [23], Neodymium has a negative coefficient, meaning the coercivity along with the magnetic energy density (BHmax) decreases with temperature. VAT price: 19.0% (included in the listed price).
