It is possible to fold the magnetic flux by combining the magnetic and non-magnetic material. I design the damping force control valve which can apply magnetic flux to the MR fluid by folding the flux. Folding of the magnetic flux allows MR fluid to generate a high damping force. In comparison with the normal damping force control valve, it is possible to generate a yield stress of about 1.5 times in the damping force control valve by folding magnetic flux.
