  That is so cool. I can only imagine what awesome things people will use this for.

    Immediately coming to mind: possible limited slip differential with electronically variable ratios

    I have a pair of magnetic finger implants. Afters seeing how detailed their printing was, my first thought was using metal as a medium to send secret messages. A magnetic brail if you will.

  It's hard to even imagine how many different places you could apply this technology in. My mind is blown.
• Mithaldu 11y ago
  So how long until these lose strength, or worse, the patterning altogether?
  • jaak 11y ago
    The FAQ claims they will loose about 1% of their strength every 100 years. http://www.polymagnet.com/faq/ http://www.polymagnet.com/faq/

      Good enough for me...
    • schoen 11y ago
      I wonder if that's linear or exponential decay. (It's hard for any user to stick around long enough to notice the difference...)

      oops, thanks.
  • martindale 11y ago
    Oh my. I'll take five.
  • Aardwolf 11y ago
    Would such springs lose magnetism after a while, or do they remain permanent?
    • Natanael_L 11y ago
      I'm guessing their magnetism will be worn down by use (they're standard magnetized permamagnets), but it will happen over years in normal circumstances. The time depends on heat, currents (should be minimal) and opposing magnetic forces (relatively small here). Also impacts.
