Title: Resisting and pulling mechanism

Abstract: A resisting and pulling mechanism comprises an excited magnetic disk and a braking wheel mounted coaxially with the excited magnetic disk which is provide with an excited magnetic coil. The braking wheel and the excited magnetic disk are separated from each other by an air gap. As the excited magnetic coil is provided with electric current, a magnetic field is effected around the excited magnetic coil. In the meantime, a magnetic flux is brought about on the excited magnetic disk. As the braking wheel is in motion, the eddy current is induced between the braking wheel and the magnetic poles of the excited magnetic disk such that the eddy current interacts with the magnetic flux to effect a rotation moment. When the excited magnetic disk is exerted on by an external force opposite in direction to the rotation moment, a resistance is effected such that the resistance can be transmitted to an external device which is connected with the excited magnetic disk via a pulley or belted wheel.
