  • its has slightly less electrons that it should, making it positively charged being repelled by your magnet.

  • which is more diamagnetic, Bismuth or Pyrolytic Carbon?

  • all diamagnetic (non magnetic) materials repel magnetic fields. You can even do that with water.

  • where can i get some to play with ? thanks / dave.

  • It all depends on where you live, how much you want and how you want to play with it!?

  • @jorgenskyt It should say the least toxic of HEAVY metals

  • Bismuth Germanate is also used to detect Gamma Rays (BGO) as scintillators

  • Bismuth is actually radioactive. It is non-toxic for the most part, but it was thought to have been stable. It's natural isotope is Bismuth-209, which decays VERY SLOWLY by Alpha emission to Thallium-205, with a Half-Life of 19-20x10^18, which is far older than our age of the universe. Even though it was found to be radioactive several years ago, it is still treated as a stable element, and it's radioactivity is very weak. Very Nice!

  • how do i know you didn't just have a magnet on a string? you need to demonstrate on both poles.

  • I will enjoy the fun.

  • It's called "Diamagentism". The crystals have cooper pair binding sites like a "Ferromagnetic" material, but they react 180 degrees to the applied magnetic field unlike a ferromagnet, which reacts in line with it. Result is the magnetic fields are the same polarity as the applied field. N to N, as it were. "Ferromagnetic" materials go N to S and are attracted. If an alloy can boost this effect the way Neodymium and Boron can for Iron, then maglev without superconductors can be made practical.

  • fantastic a single-fact metal but where is its property from?

  • Its not really known as the least toxic of all metals, but it is the least toxic from Lead,thallium and the other metals in that period of row.

  • Fantastic...!!
