To demonstrate forces and acceleration on an object from a magnet.


Gauss Rifle track, 7 ball bearings, 2 strong magnets (all kept as one piece in storage)


  • Set the track on a level surface on a support to stay upright.
  • Place 3 ball bearings in a row in front of each of the two magnets.
  • Take the last ball bearing and place it at the very end of the track (on the far side of the magnet from the other ball bearings).
  • Give the bearing a small roll towards the first magnet.
