  Vortons are extended superconducting rings, which hypothetically may play a
role in cosmology and even may have significance in connection with cosmic rays
of high energy. Some of these objects are able to confine fermions which
consequently become massless in the core of the object \cite{witten},
\cite{vorton3}. These fermions travel at light speed in the core and may
generate a large current without dissipation. This raises interest about the
generation mechanisms for these currents inside the defect. This question is
analyzed here by studying the inverse photoelectric effect for these objects
namely, the absorption of a fermion with the consequent emission of a photon or
a massive boson by the extended defect. Another motivation for the present work
is that there exists a discussion in condensed matter about the role of the
bound spectrum in the macroscopic Magnus force that the vortex experiences in
certain type of superfluids or superconductors. The discussion is about wether
the main force comes from scattering of these fermions by the object or by the
effect of the environment on the bound states in the object, which may induce a
spectral flow leading to an effective macroscopic force \cite{pelea1},
\cite{pelea2}, \cite{pelea3}. Without claiming that the results described here
are conclusive in the context of condensed matter, this work presents a
comparison between these two effects for vortons interacting with a plasma of
fermions.
