چکیده:

In the following research, the persistent current and low-field magnetic susceptibility in the presence of uniform magnetic field have been evaluated. In ordered rings, the variation of low-field magnetic susceptibility with the number of electrons Ne indicates the diamagnetic sign of the total persistent current for even and odd Ne in the limit (), while in disordered ones, it shows that the persistent current has diamagnetic (paramagnetic) sign for odd (even) number of electrons
