      BEST SOLUTION Finite Element Analysis Consultancy 

High Field Hybrid Magnet 

Best Solution's customer, Oxford Instruments are world leaders in the design and manufacture of special superconducting magnets. Best Solution were able to provide modelling support on a high field, hybrid magnet project, which used a combination of superconducting, and copper coils, for a magnet with a bore flux density of up to 40 Tesla. 
 
The challenges in the magnet design were extreme, and transient modelling of coupled magnetic-stress and magnetic-thermal-stress fields were required in order to enable parts of the structure to be designed to withstand the enormous forces of a quench.
