This is an analytical study of magnetic fields effects on the conductance, the shot noise power, and the third charge-transfer cumulant for the Aharonov-Bohm rings and the Corbino disks in graphene. The two distinct physical mechanisms lead to very similar magnetotransport behaviors. Differences are unveiled when discussing the third-cumulant dependence on magnetic fields.

(7) is replaced by [10]: $ϕ' ≡ Φ_1/Φ_{AB} + 4π/Φ_0 ∫_{r_1}^{r_2} dr/r ∫_{r_1}^{r} dr'r'B (r)$, where $Φ_1$ is flux through the inner ring ($r<r_1$). In particular, if B(r)=0 for $r>r_1$, the Aharonov-Bohm-like oscillations occur when varying $Φ_1$
