Abstract: An electric adjustable magnetic control damper comprises a force applied unit, a magnetic control unit, a driving unit, and a control unit; a driving rod drives the force applied unit displaced linearly, and a screw sleeve for the screw sleeve to displace linearly and for the screw rod and the magnetic ring to be rotatable, the magnetic control unit has a fixing seat able to displace linearly, and the fixing seat has a the permanent magnet, the driving unit has a motor and a gear train, the control unit can input the required damper value to drives the motor to rotate; whereby the motor and the gear train drives the fixing seat displaced, and create a required gap between the permanent magnet of the fixing seat and the rotor of the magnetic ring to create eddy load for being dampers of axial displacement of the driving rod and rotation of the rotor, and the damper achieves the effect of fitness exercise.
