Adjustable variable resistance device based on magnetorheological effect

The invention relates to an adjustable variable resistance device based on the magnetorheological effect. The adjustable variable resistance device comprises a first magnet, a second magnet, a closed type sheath and a base, wherein a magnetorheological material is arranged in the closed type sheath; two electrodes are respectively arranged on the upper surface and lower surface of the closed type sheath; two lead wires are respectively connected with the two electrodes; rotating shafts are fixed on the front surface and rear surface of the closed type sheath and inserted into circular holes of two fixed support frames with two corresponding sides; and the first magnet, the second magnet and the fixed support frames are arranged on the base. The adjustable variable resistance device based on the magnetorheological effect, which is disclosed by the invention, can provide the resistance ranges which accord with different intervals according to actual demand by changing the strength of an external magnetic field and the variety and concentration of the magnetorheological material.
