Magnetic field sustained by the elastic force in neutron star crusts

We investigate the magneto--elastic equilibrium of a neutron star crust and magnetic energy stored by elastic force. The solenoidal motion driven Lorentz force can be controlled force, so that conditions for field strength geometry are less restrictive. For models, minor part is balanced weak because irrotational dominant gravity pressure forces. Therefore, strong may confined in interior, regardless poloidal or toroidal components. numerically calculated axially symmetric models with maximum shear--strain, found $> 10^{46}$ erg crust, even normal surface dipole-field-strength ($<10^{13}$ G). much exceeds ($ 10^{44} -10^{45}$ erg). shear--stress spatial distribution revealed structure likely to break down near surface. In particular, critical position highly localized at depth than 100 m from
