The elastic properties of the flux line lattice (FLL) in type II superconductor are calculated from the Ginzburg Landau theory for large induction H c1 ≪ H ⪅ H c2 . It is obtained that the elastic response of FLL to the localized perturbation field is non‐local generally. The change of magnetic field caused by the deformation of FLL is expressed by the integral with kernel vanishing in the distance . It leads to the effective interaction between flux‐lines with range and amplitude proportional to −2 . The influence of the surface of the superconductor on FLL deformation caused by the normal inclusions is obtained.
