  • - What do you think about this? see, and tell us now.
  • - haha they're having so much fun and so would I <3
  • - lol
  • - zaibis! :)
  • - Having those two magnets close together is a seriously fucking stupid idea.
  • - Alot
  • - That is the cutest tiny little dewar flask I have ever seen.
  • - Redneck russians?
  • - You should get professional help.
  • - I said to myself `russians` as soon as I saw the liquid nitrogen and bare hands.
  • - i soviet Russia gloves need your hands
  • - Причиной есть факт, что медь к примеру является хорошим и накоротко замкнутым проводником, если его поместить в переменное магнитное поле, то в нем начнут возникать токи, которые собственно генерируют внешнее магнитное поле, которое и взаимодействует с полем постоянного магнита, но только когда этот магнит движется(например падает в трубку), если он будет просто лежать, ничего не будет. А усиливается эффект при низкой температуре потому, что снижается сопротивление, следовательно токи мощнее.
  • - Looks like these guys will try to reproduce the Tunguska event someday.
  • - did the liquid nitrogen turn metal into slightly magnetic? if i pour LN on my pen15, would that make it attract metal?
  • - The easiest way to begin to understand superconductors you could say
  • - nice vid nigga keep up the good work!
  • - MAGNETS FOR DUMMIES
  • - THE IMPLICATIONS OF THIS MONUMENTAL DISCOVERY: WEARING A SUIT OF NEODYMIUM MAGNETS INSIDE A GIANT COPPER TUBE = ANTIGRAVITY S
  • - Yes, I agree
  • - no. It's copper they used. Copper / aluminum conduct the electricity generated from the neodymium's magnetic field. The Nitrogen just amplifies it.
  • - 2:01 xDDDDDDDDDDDDDDDDDD
  • - lol, idiots with liquid nitrogen is always a good idea.
  • - HOLY SHIT DUDE!!!!
  • - This guys are asking for it! High precaution should always by taken when working with strong magnets and liquid nitrogen,
  • - Best part is 2:00 - 2:03.
  • - fuck gloves, im batman
  • - The magnet induces an electric current in the copper, due to a magnetic field moving through a conductor. Said current is then "short circuited" through the copper, since it's just one solid piece, and the energy is turned from motion of the magnet into heat in the copper, since kinetic energy is taken out of the magnet, it slows down. The liquid nitrogen just makes the copper a better conductor, which lets the magnet induce current in it more efficiently, slowing it down more.
  • - safyt first boy great vid
  • - two minutes in, using a magnet that just about picks up and holds copper and is that silver or gold?
  • - а понятно
  • - Messing around with superconductors heh ? :P
  • - прикольно!, с ними (с магнтоми) можно и пальчики отщемить а что это за медальен аурум чтоли?
  • - Don't drink Vodka during lab experimentation.
  • - Маленький слиток из сильвера, на котором написана чистота и вес 50г.
  • - Somebody needs to call the Mythbusters, just so we can watch them ramp this up to 11.
