  • Thank you very much, so simple so useful, very clear , thanks again

  • thank you for explaining this! i was getting frustrated with the needle on a leaf trick. it kept going the opeset way

  • where did u get the one wit the N and S already on it, and is it strong?

  • @cooliopoolio123 From memory I purchased the magnets from Dick Smith or Jaycar (in Australia). In the UA that would be Radio Shack or Tandy. The N and S were not white when I purchased the magnets - I used whiteout fluid to paint the N and S to make them stand out more in the video.

  • A fun project for children is to lightly scratch one end of a crewel needle onto the surface of a magnet, then carefully lay that needle flat on a bottle cap or piece of cork or foam, free floating on a water surface. ^_^
