A device for reeording parabolie trajectories using the magnetie adsorption principle is designed bymethods such as multi-sereen method, technical contradietion, and the ideal final result in the theory olinventive problem solving, ( TRIZ ) .It is suitable for teaching or home autonomous learning and does not requireeleetric drive.lt is a parabolic trajectory recorder that causes the target ball to move on a vertical plane throughspheres collisions at different angles , and the magnetic force of the target ball adsorbs iron powder particlesattached to the frosted coordinate plane to form a continuous parabolie trajectory.It has the characteristics oleombination ,portability , and versatility.
