Abstract: In this paper， the potential various coupling mechanisms between the magnetic field and the sonoluminescing bubble were studied by a theoretical estimation method.The phenomenon of bubble sonoluminescence is an important way to reveal the mechanism of ultrasound cavitation.The magnetic field effects on the sonoluminescing bubble were studied from three areas， including outside the bubble， the bubble surface and inside the bubble.We also pointed the degree of importance of all possible various coupling ways bettwen the magnetic field and the sonoluminescing bubble and infered a interaction mechanisms from the effects.

Key words: approximate estimation, sonoluminescence, magnetic field, coupling mechanism
