In this paper we investigate the semiclassical behavior of the lowest eigenvalue of a model Schrödinger operator with variable magnetic field. This work aims at proving an accurate lower bound for this eigenvalue, the corresponding upper bound being already proved in the general case. The present work also aims at establishing localization estimates for the attached eigenfunctions.
