Rare-earth permanent magnets are the magnets made with addition of elements of lantanoidny group
alloys neodymium - iron-pine forest (Nd Fe B) and samarium-cobalt (SmCo) are most often used.
Magnetic materials on the basis of rare-earth metals have higher magnetic parameters in comparison
High specific magnetic energy and resilience to the degaussing fields do rare-earth magnets
irreplaceable in systems of devices and devices with high intensity of magnetic fields, also open opportunities
reduction of dimensions of components.
Advantages of rare-earth magnets: higher magnetic parameters in comparison with ferrite magnets,
possibility of creation of strong magnetic fields at the small sizes, high temperature and temporary stability,
working temperature is up to 250 °C
Scope of rare-earth magnets: computer equipment, speaker systems, aircraft equipment,
electrical machines and devices, magnetic couplings.
