Molecular spin alignment having macro torque effects?

Hello,

If a magnetic field aligns the electron or nuclear spins can that have a macro effect of causing torque? So for example if we had a rod and we fixed one end but allowed it to freely rotate and then aligned electron or nuclear spins would that cause the rod to rotate?

Thanks,

And the opposite effect is the Barnett effect, whereby mechanical rotation of a ferromagnetic body on its axis results in magnetization along the rotational axis.
