Pulsed magnets of 60 tesla or more with a flat-top of 100 ms (quasi-continuous) are among the user facilities to be provided by the NHMF. The design of such magnets is constrained by available materials and thermal recycle time. The design path discussed here tailors materials and current densities of independent concentric coils. The progressive design steps are illustrated by a specific example of an eight-coil, 60T magnet. In the preliminary design stage closed form calculations of magnetic, structural, thermal, and electrical circuit behavior are used to achieve a practical design that meets initial requirements. Design refinement incorporates finite element analyses and test results on materials, fabrication and prototypes. Higher fields are possible without large changes.
