Effect of a strong magnetic �eld on different properties of a single sonoluminescing bubble has been studied theoretically with regard to the experimental report of Young et al. [Phys. Rev. Lett. 77, 4816, (1996)]. We performed a hydrochemical simulation including the magnetic �eld force on electric dipole moments of liquid molecules surrounding the bubble. We obtained that at constant pressure forces, the presence of magnetic �eld reduces the bubble equilibrium radius. This generates a decrease in the violence of bubble collapse and the peak temperature attainable at the end of it, which �nally results in a reduction in the sonoluminescence radiation intensity. Our simulation also shows that the magnetic �eld considerably increases the pressure threshold of disappearance of a sonoluminescing bubble and the concerned calculation results are in a good quantitative agreement with the available experimental data.
