The Samarium Cobalt Disc Magnet

About the sametime as Alan from Sekao Engineering was starting his first Boilermakers apprenticeship. Karl Strnat of the Wright-Patterson Air Force Base and Alden Ray from the University of Dayton, had started the development of a new rare earth magnet. Samarium Cobalt disc magnets are one of the modern rare earth magnets. Developed in the 1960’s they have been used in many industries and applications since.

One of the main drawbacks to Samarium Cobalt Disc Magnets is the price fluctuations on Cobalt, which is a very price sensitive commodity. However, SmCo are extremely resistant to demagnetization. And, they can withstand high temperatures up to 800 °C.

From hobbies to Military and Space, SmCo put to good use

Additionally, Samarium Cobalt disc Magnets are used in slot car racing. This is a hobby, racing with powered miniature cars. However, you can use other vehicles. These cars, are guided by grooves or slots in the track. The SmCo magnets help turn the motors.

Partly Due to the expensive nature, Sm-Co magnets are rarely used domestically. Mainly now getting used by military and space applications. But this is also because they can hold large magnetic fields at high temperatures. In comparison, other rare earth magnets lose their field strength at higher temperatures. For instance, adding cooling apparatus to a tank would increase the weight and take up space.

Samarium Cobalt Magnets keeping you safe

Interestingly, Samarium Cobalt Disc magnets are used by the latest F-15 (Lightning II) aircraft. This is because the magnet remains reliable over the entire militarily-relevant temperature range. This range can go from extreme cold to extreme heat in seconds. Normally under powerful G-forces. Samarium Cobalt has ultimately assumed a role as a key component of the latest electronic warfare system. Helping to get the F-15 to an altitude of 70,000 feet.
