The invention discloses an electromagnet device for a safe box. The device comprises a casing, an end cover, a lock, an electromagnet body and a limit pin. The device is characterized in that the end cover is connected with the casing, a cavity adapted to the lock, an upper groove adapted to the electromagnet body and a lower groove adapted to the limit pin are formed in the casing. A rotation shaft I adapted to the lock is arranged in the cavity, a torsion spring I connected with the lock is arranged on the rotation shaft I, a lower spring is arranged on an iron core of the electromagnet body, the iron core penetrates the cavity to be in limit connection with the lock, an upper spring is arranged on the limit pin, and the head of the limit pin penetrates the cavity to be adapted to the lock. The device has the advantages that a multi-unlocking protection function is provided, and good anti-theft and safety performances are still provided during strong shaking or impacting.
