A dumbbell ball-point pen is provided to reduce diseases of the modern persons and to help mental health by enabling users to exercise and stretch by generating a magnetic field at both sides by applying electricity, and changing the weight according to electrical power. A dumbbell ball-point pen is used as a dumbbell by using electrical power. The dumbbell ball-point pen regulates the weight by using the gravity and electrical power. The dumbbell ball-point pen is composed of a ball-point pen core, a ball-point pen rod, two magnetic plates using the electrical power, and a battery. The magnetic fields generated at both sides keep the horizontality with exactly same force. The same force is applied all the time in regulating the gravity. |
