  • Aluminium ist paramagnetisch...!

  • you have a tromendous amount of energy being created,,,,,any way to tap it. I was thinking series of pipes joined together every second one creating ac volts....??

  • there's not that much energy to be had from a small magnet falling - see the write-up for my lego weight driven generator.

    Your thoughts are more or less how a shaker-light works... something to bear in mind; low resistance (pipe) = low volts high amps, high resistance (coil of wire in shaker-light) = high volts, low amps

  • yep... eddy current braking is used on roller coaster rides :)

  • Its not called eddy current, its called Lenz effect

  • 'eddy current braking' can be described by Lenz' Law... the conservation of energy in electromagnetic systems... however, the electrical currents within the aluminium (creating the magnetic forces that slow the magnet) are turbulent, i.e. an eddy... hence the term 'eddy current'... something that is being forceably slowed can be said to have had braking applied... 'eddy current braking'

  • Whilst you may technically be correct, the term Lenz effect has little meaning... have a google for both 'lenz effect' and 'eddy current braking'

  • @wldcld9

    No, what he means is eddy is the guy running the ride, using the Lenz effect, he just forgot to mention it.

  • awesome

    on a side note, way to spell through.

  • thanks... i spelled threw right in the side notes?

  • that was fun...

  • cool

  • ok!

  • how come it does dat?

  • the answer to your question can be found by searching google for 'eddy current braking'

  • Fascinating

  • maybe you can LEARN proper ENGLISH grammar before you even said you did.

  • I tryed this experment before you eaven posted this vid

  • realy?

    what makes you say that?

  • i think it works because copper is more conductive (less resitivity) than aluminum, so the eddy currents would be stronger

  • Neat! Can normal magnets o this.The magnet looks lika neodymium

  • i never tried with normal magnets... yes it's a neo & i have 1000+ of diff sizes stuck on my fridge... so neos seem normal to me :)
