Complementarity bilateral bounds on forces in magnet systems
Résumé
It is well known that complementarity can provide bilateral bounds on energy, in numerical approximations of nonlinear magnetostatics. Force is, up to sign, the derivative of energy, so can such bounds also apply to forces, torques, etc.? On the face of it, no, since inequalities are not preserved by differentiation. Yet, useful bounds can be given in some cases, as shown here, following an idea by E. Matagne (Eur. J. Appl. Phys., 25, 107 (2004)).
