  We discuss the possibility of new generation neutrino and astroparticle
physics experiments exploiting a superconducting magnetized liquid Argon Time
Projection Chamber (LAr TPC). The possibility to complement the features of the
LAr TPC with those provided by a magnetic field has been considered in the past
and has been shown to open new physics opportunities, in particular in the
context of a neutrino factory. The experimental operation of a magnetized 10 lt
LAr TPC prototype has been recently demonstrated. From basic proof of
principle, the main challenge to be addressed is the possibility to magnetize a
very large volume of Argon, corresponding to 10 kton or more, for future
neutrino physics applications. In this paper we present one such conceptual
design.
