It is well known that in noncentral heavy ion collisions a transient strong magnetic field is generated in the direction perpendicular to the reaction plane. The maximal strength of this field is estimated to be eB similar to m(pi)(2) similar to 0.02 GeV2 at the Relativistic Heavy Ion Collider and eB similar to 15m(pi)(2) similar to 0.3 GeV2 at the LHC. We investigate the effects of a strong magnetic field on B and D mesons, focusing on the changes of the energy levels and the masses of the bound states. Using the color evaporation model we discuss the possible changes in the production of J/psi and Upsilon. (AU)
