In the AdS/CFT framework meson thermalization in the presence of a constant external magnetic eld in a strongly coupled gauge theory has been studied. In the gravitational description the thermalization of mesons corresponds to the horizon formation on the avour D7-brane which is embedded in the AdS5S5 background in the probe limit. The apparent horizon forms due to the time-dependent change in the baryon number chemical potential,the injection of baryons in the gauge theory. We will numerically show that the thermalization happens even faster in the presence of the magnetic eld on the probe brane. We observe that this reduction in the thermalization time sustains up to a speci c value of the magnetic field
