La génération de champs magnétiques pulsés très intenses par des bobines non destructives est limitée par les forces de Lorentz s’exerçant sur les matériaux transportant le courant, créant des contraintes mécaniques pouvant conduire à la plastification voire à la rupture des bobines. Afin de produire les bobines de fort champ, le LNCMI-Toulouse est engagé dans le développement de conducteurs :

 renforcés macrocomposites (cuivre gainé d’acier inoxydable, résistance à la traction : 1 GPa) pour les bobines monolithiques conventionnelles ou à densité de renfort optimisé

 ultra-renforcés nanofilamentaires (cuivre/niobium, cuivre/tantale, résistance à la traction : 2 GPa) pour les bobines gigognes de type Coilin/Coilex produisant des champs magnétiques supérieurs à 80T
