  We investigate the properties of a two-dimensional quantum ring under
rotating and external magnetic field effects. We initially analyse the Landau
levels and inertial effects on them. Among the results obtained, we emphasize
that the rotation lifted the degeneracy of Landau levels. When electrons are
confined in a two-dimensional ring, which is modeled by a hard wall potential,
the eigenstates are described by Landau states as long as the eigenstates are
not too close to the edges of the ring. On the other hand, near the edges of
the ring, the energies increase monotonically. These states are known as edge
states. Edge states have an important effect on the physical properties of the
ring. Thus, we analyze the Fermi energy and magnetization. In the specific case
of magnetization, we consider two approaches. In the first, we obtain an
analytical result for magnetization but without considering rotation. Numerical
results showed the de Haas-Van Alphen (dHvA) oscillations. In the second, we
consider rotating effects. In addition to the dHvA oscillations, we also verify
the Aharonov-Bohm-type (AB) oscillations, which are associated with the
presence of edge states. We discuss the effects of rotation on the results and
find that rotation is responsible for inducing Aharonov-Bohm-type oscillations.
