Magnetic Spin

Two kinds of sources of torsion, aligned spin and macroscopic rotation, are demonstrated by analyzing the Lagrangian. In the case of Dirac particles as a direct sensor for torsion, the torsion spin effects are strongly influenced by the backgrounds, which are magnetic spin, rotation spin and gravity spin. Increasing the source of the torsion is equivalent to increasing the background itself. The first proposed criterion for torsion detection is that any astrophysics experiments have no hope of showing the evidence for torsion directly. The promised evidence for torsion must be cumulative and indirect on the neutron star. The macroscopic rotating body, an indirect sensor for torsion, has not been able to present the trace of the torsion in the experiments carried out so far.

Magnetic Spin

On the basis of rotation-spin, torsion-spin and magnetic-spin effects, by which the spin precession arises the polarized magnetic field of neutron star to incline to the rotational axis. In the case of accretion layer structure of the recycled pulsar and the companion star magnetic influence considered, the magnetic inclinations of the recycled pulsars are different from that of the normal radio pulsars. The theoretical conclusions and consistent observational evidence is discussed.
