Examination of an influence of winding geometry and operating temperature on basic parameters of superconducting coils made of MgB2 wire - Theoretical analysis

► Theoretical model was developed and applied to cylindrical MgB2 coils. ► Influence of winding geometry on basic parameters of coils was studied. ► Critical current, magnetic field and stored energy of coils were calculated. ► Winding geometry optimization was performed with respect to overall wire length. ► Wire length can be considered as a key factor determining the cost of HTS magnet.
