Magnetoreceptor existing in the living beings is the mechanism supporting the biological magnetic navigation, and the process of magnetic information transforming to neural signals is the key process of magnetoreceptor mechanism, however it is still hypothesis. In this paper, the process of magnetic information transforming to nerve signals of the mechanism of electromagnetic induction, magnetic protein biocompass and magnetite-based magnetoreceptor are characterized, and then a possible way to cognize the process of magnetic information transforming to nerve signals from the point of view of theory is presented .
