  We use the gauge/gravity correspondence to show that in its context there
appear Landau levels when studying the excitations of the fundamental degrees
of freedom of a strongly coupled plasma subject to a magnetic field of
arbitrary intensity. We work in the phase where mesons are melted by embedding
a D7-brane in the 10D uplift that we construct for the 5D background associated
to a magnetic brane. By studying the dependence of the lowest quasinormal
frequency on both, the intensity of the magnetic field and the Landau level, we
corroborate that the energy behaves as expected for dissociating Landau levels.
The reconstruction of the impact of the magnetic field on the stability of the
quasinormal modes allows us to identify inverse magnetic catalysis for
intensities of the field bellow a certain value, and magnetic catalysis for
those above it.
