A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton .
An important use of samarium is samarium–cobalt magnets, which are nominally SmCo 5 or Sm 2 Co 17. [104] They have high permanent magnetization, about 10,000 times that of iron and second only to neodymium magnets. However, samarium magnets resist demagnetization better; they are stable to temperatures above 700 °C (1,292 °F) (cf. 300–400 ...
Samarium–cobalt magnets are made from an alloy of samarium and cobalt, known for their high magnetic strength, excellent temperature stability and resistance to demagnetization. [4] They are often used in applications requiring powerful and stable magnets, such as in motors, aerospace, military equipment, and high-temperature environments. [5]
Samarium–cobalt magnets (chemical formula: SmCo 5), 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, samarium–cobalt has a higher Curie temperature, creating a niche for these magnets in applications where high field strength is ...
A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.
This plant, the first unit of IREL, was made operational way back in 1952 for processing of monazite, whose capacity was subsequently increased by about three times.Rare Earths Division (RED), Udyogamandal, Aluva is located on the banks of Periyar River in Kerala at a distance of 12 km from the port city of Kochi and 15 km from Kochi International Airport.
China paid Ceylon Rs. 1.74 per pound of rubber, whereas the average world market price was Rs. 1.05 per pound. This premium varied with every five-year agreement. The handling charge, which was fixed at five cents per pound, also varied in subsequent years. China also agreed to supply rice to Sri Lanka below market prices, at £54 or Rs. 720 ...
