Static magnetic field of 0.2-0.4 T promotes the recovery of hindlimb unloading-induced bone loss in mice.

Together, our findings suggest that SMF of 0.2-0.4 T facilitated the recovery of unloading-induced bone loss by inhibiting the increase of bone resorption in reloaded mice, and indicate that SMF might become a promising biophysical countermeasure for maintaining bone health in astronauts after landing.
