The invention discloses a method, a device and a system for demagnetizing a magnetorheological suspension. The method comprises the following steps: acquiring excitation coil control current of the magnetorheological suspension and magnetic induction intensity of a magnetized piston iron core in real time; whether demagnetization processing is carried out or not is judged according to the excitation coil control current collected in real time and the magnetic induction intensity of the magnetized piston iron core, the existence of residual magnetism can be recognized in time, the residual magnetism is eliminated, and therefore agglomeration and sedimentation are reduced, it is guaranteed that the performance of the magnetorheological damper is stable, and the control precision is improved conveniently. And real-time signal sampling is carried out on the exciting current and the magnetic induction intensity of the piston iron core, so that detection and feedback control on the demagnetization effect can be realized.
