Definitions

  • the present invention relates to a modified classical spinning top (using permanent magnets and no mechanical restraints ) that can be horizontally driven without the modification of the rotation movement.
  • Spinning tops are old toys . They are built from wood , metals, or plastics in different shapes , colors and dimensions. Recently some of them produce a sound or/and light. Not much has been changed since the beginning. Once it is put into rotation we just look at its movement . No possibility to change the movement, to interact with it.
  • Gyroscopes are well known toys and devices. They fascinate how the direction is kept constant.
  • Permanent magnets are used to obtain different configurations using balls , nails, ferromagnetic powder , magnetic fluids. Once the configuration is achieved nothing can happen more , no more fun.
  • the disk of the spinning top is a permanent magnet above a second permanent magnet in the repulsion configuration .
  • the spinning top can levitate if some conditions are fulfilled .
  • the levitation is not so easy to be obtained .
  • Levitron is produced by : www.supermagnete.de .
  • Another toy - Magnetic UFO Spinning Top - has a small permanent magnet at the bottom that is in contact with a ferromagnetic planar piece. During rotation the bottom of the spinning top moves the planar piece in an interesting manner.
  • the present invention is directed to a spinning top with a controllable horizontal motion.
  • L, N are the angular momentum and torque respectively.
  • To move the top horizontally it is necessary to act on it with a force that passes the rotation axis (to have a torque equal with zero). This can be realized by the interaction of attraction of the two permanent magnets ; one on the axis of rotation , coaxial with it and another one above the top.
  • FIG. 1 A general view of the modified spinning top.
  • FIG. 2 Detailed view of the permanent magnet at he upper part of the top
  • FIG. 3 The collision of two cylindrical shaped tops.
  • FIG. 4. The suspended top into rotation.
  • FIG. 5 The collision between two tops :one with a hexagonal shape and another one with a cylindrical shape.
  • FIG. 6 The collision between a top with a hexagonal shape and a ball.
  • top and permanent magnets did not achieve a controllable dynamics for tops.
  • the dynamics of a modified gyroscope (I.Grosu, Romania Patent No. 91 857) is controllable by using an external magnetic field.
  • This idea is used here .
  • the key idea is to modify a classical spinning top by using a permanent magnet on the rotation axis , at its upper part , coaxial with it .
  • An external permanent magnet manually moved above the top , attracts the first magnet moving the top horizontally.
  • the rotation motion is not changed because the torque of the attraction force between two permanent magnets is zero. This happens because the direction of this force passes the rotation axis. So the horizontal translation motion of the top can be controlled by the motion of the external permanent magnet.
  • the top with a controllable dynamics has much more interest and fun and educational and scientific achievements.
  • a classical spinning top 1 is modified by using a small permanent magnet 2 on the rotation axis 3 , coaxial with it , at its upper part.
  • a second permanent magnet 4 is above the top into rotation 5.
  • the top moves horizontally 6 following the horizontal motion 7 of the permanent magnet 4. The motion 6 is obtained only if the motion 7 is slow. At rapid movement 7 the top is not able to follow it.
  • the top with controllable dynamics can be used to realize several games. I propose here 3 variants.
  • a competition game can be realized by using a hexagonal shaped top 9 and a ball lO.
  • the ball 10 moves horizontally.
  • Two players each having a hexagonal shaped top 9 hit the ball(Fig. 6) in order to move it in the others gate.
