Debye proposed the generation of electric potential difference under acoustic excitation in electrolyte solution because of ion separation. However, the ion separation can also induce magnetic field, which has always been neglected by researchers. This paper builds a theoretical model of Debye effect magnetic field, and a multi-physics computation method to study the magnetic field. According to the computation results, an acoustic excitation with frequency at 70Hz and amplitude at 0.1m/s can generate magnetic field at the level of one pico-Tesla, which can be detected nowadays.
