Samarium Cobalt magnets are available on request due to end-use considerations. Please contact us for supply. The SmCo Halbach Array ring is made from 16 magnets (22.5 degree arc segments, each with a specific direction of magnetisation). Each arc segment has the direction of magnetisation such that the magnetic field traverses the central air gap and is then ‘guided’ through and around the magnet material itself. This particular array is special as it is fully contained and uses cryogenic adhesive so that it can be used at liquid helium temperatures of -269 deg C.
