These samarium–cobalt magnet alloys (generally written as SmCo 5, or SmCo Series 1:5) have one atom of rare-earth samarium per five atoms of cobalt. By weight, this magnet alloy will typically contain 36% samarium with the balance cobalt. [9] The energy products of these samarium–cobalt alloys range from 16 MG·Oe to 25 MG·Oe, that is ...
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. Rare-earth magnets are extremely brittle and also vulnerable to corrosion, so they are usually plated or coated to ...

U.S. President Donald Trump on Monday told the Pentagon to find better ways to procure a rare earth magnet used in specialty motors, warning that the nation's defense would suffer without adequate ...
Introduced in 2004, they were similar to the Vintage Noiseless pickups, but Lawrence's research into controlling magnetic eddy currents led him to employ miniaturized samarium cobalt alloy magnets instead of Alnico V. Samarium cobalt is a rare earth magnet that is more powerful than the Alnico V magnets traditionally used in pickup design.
