As we have recently proposed study magnetic fields can modify dramatically the nuclear structure leading, e.g., to a change of shell-correction components of binding energies and nuclear magic numbers. In this contribution we further demonstrate that the predominant mechanism of such a modification can be interpreted as a phase-shift in shell-oscillations originating from a field dependent interference of contributions coming from majority- and minority-spin energy levels. Nuclear magic numbers corresponding to the vicinity of the stability line depend on the magnetic field and are changed considerably at the strength scale $Bsim 10^{16} - 10^{17}$ G relevant, e.g., for supernovas and neutron stars. At such a field strength the magic nuclei of the iron region are shifted towards smaller mass numbers.

The neutron star crust magnetodynamics is demonstrated to exhibit erraticjumps at the fields corresponding to the sharp change of nuclide magneticmoments induced by quantization effects. Such a noise originates frommagnetic avalanches and shows intensity and statistical properties which arefavorably compared to the burst activity of soft repeaters.

The magnetization of neutron star matter is considered within the thermodynamic formalism. The quantization effects are demonstrated to result in sharp abrupt magnetic field dependence of nuclide magnetic moments. Accounting for inter-nuclide magnetic coupling we show that such anomalies give rise to erratic jumps in magnetotransport of neutron star crusts. The properties of such a noise are favorably compared with burst statistics of Soft Repeaters.
