  The present work studies the dynamics of axion quark nuggets introduced in
\cite{zhitnitsky} and exploited in the works
\cite{zhitnitsky2}-\cite{zhitnitsky13}. The new feature considered here is the
possibility that these nuggets become ferromagnetic. This possibility was
pointed out in \cite{tatsumi}, although ferromagnetism may also take place due
some anomaly terms found in \cite{son}-\cite{son2}. The purpose of the present
letter however, is not to give evidence in favor or against these statements.
Instead, it is focused in some direct consequences of this ferromagnetic
behavior, if it exists. The first is that the nugget magnetic field induces an
electric field due to the axion wall, which may induce pair production by
Schwinger effect. Depending on the value of the magnetic field, the pair
production can be quite large. A critical value for such magnetic field at the
surface of the nugget is obtained, and it is argued that the value of the
magnetic field of \cite{tatsumi} is at the verge of stability and may induce
large pair production. The consequences of this enhanced pair production may be
unclear. It may indicate that the the nugget evaporates, but on the other hand
it may be just an indication that the intrinsic magnetic field disappears and
the nuggets evolves to a non magnetized state such as
\cite{zhitnitsky}-\cite{zhitnitsky13}. The interaction of such magnetic and
electric nugget with the troposphere of the earth is also analyzed. However, if
the magnetic field does not decay before the actual universe, then this would
lead to high energy electron flux due to its interaction with the electron
gases of the Milky Way. This suggests that these magnetized quarks may be a
considerably part of dark matter, but only if their hypothetical magnetic and
electric fields are evaporated.
