We consider the Dirichlet Laplacian with uniform magnetic field on a curved strip in two
dimensions. We give a sufficient condition on the width and the curvature of the strip
ensuring the existence of the discrete spectrum in the strong magnetic field limit, answering
(negatively) a conjecture made by Duclos and Exner.
