Rare-earth magnet - Wikipedia
The magnetic field typically produced by rare-earth magnets can exceed 1.2 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla. There are two types: neodymium magnets and samarium–cobalt magnets. See more Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing … See more The rare-earth (lanthanide) elements are metals that are ferromagnetic, meaning that like iron they can be magnetized to become permanent magnets, but their Curie temperatures (the … See more Samarium-cobalt Samarium–cobalt magnets (chemical formula: SmCo5), the first family of rare-earth magnets invented, are less used than neodymium magnets because of their higher cost and lower magnetic field strength. However, … See more The United States Department of Energy has identified a need to find substitutes for rare-earth metals in permanent-magnet technology and has begun funding such research. The See more Some important properties used to compare permanent magnets are: remanence (Br), which measures the strength of the magnetic field; coercivity (Hci), the material's … See more The greater force exerted by rare-earth magnets creates hazards that are not seen with other types of magnet. Magnets larger than a few … See more Since their prices became competitive in the 1990s, neodymium magnets have been replacing alnico and ferrite magnets in the many applications in modern technology requiring powerful magnets. Their greater strength allows smaller and lighter magnets to … See more WebToday, the magnetic materials the engineer has to work with are silicon steel, nickel iron (permalloy), cobalt iron (permendur), amorphous metallic alloys, and ferrites. These also … WebPermeability is the ability to support formation of magnetic fields in a material. Permeability is measured in H/m (henries/m) or newtons/ampere 2 (N/A 2).. The Permeability of Free Space. The permeability of free space µ 0 (the permeability constant or the magnetic constant) is. µ 0 = 4π 10-7 (H/m) . ≈ 1.257 10-6 (H/m, N/A 2).
