Changeable Dumbbell / Dumbbell

The dumbbell acts as the magnetic south pole and the blanket as the magnetic north pole. According to the theorem of Heteropolar phase suction, the user can utilize the attraction (equivalent to gravity) between the dumbbell and the blanket to take exercise. Through the controlling pad, the user can adjust the weight needed to an appropriate level while the dumbbell will consequently change the amperage automatically, thus change the electromagnetic force, resulting in the change of attraction ultimately.
