Magnet Through a Copper Pipe=AWESOMESAUCE!

My wife shared this with me.

I have GOT to find the right goodies and do this myself!!

This Is What Happens When A Magnet Is Dropped Through A Copper Pipe
The Mind Unleashed

When a magnet is dropped down a conducting copper pipe, it feels a resistive force (assuming that magnets have feelings).

The falling magnet induces a current in the copper pipe and, by Lenz’s Law, the current creates a magnetic field that opposes the changing field of the falling magnet. Thus, the magnet is “repelled” and falls more slowly.

Good Stuff Sledge! The simplicity and the complexity of scrapping keeps me wanting more. Thanks for sharing that and thanks to your wife too!

The pipe would be really cool, but you can get the idea on a flat surface. The magnet test is supposedly a test for silver coins. If you tip a silver coin at a 45 degree angle and slide a rare earth magnet down the coin face, it will slowly slide at a speed far less that one would expect the magnet to slide. I say "supposedly" because, although this works, it will do the same thing with brass or copper, so.... One can reeeelly get the idea if you have a brass or copper tray. Slide the RE magnet down and watch it "defy" gravity. Amaze your friends. Get girls. See through clothes x-ray powers.... order yours today!

Works like a charm. I just took a piece of 1/2" copper pipe and dropped a RE magnet down it. Took about 4 seconds to drop 7 feet.

Ill take about 15 of those pipes

Definitely don't get your hand caught between that magnet and an anvil.

Thats the idea for the new hover boards. really cool to watch.

I did it as well with a 1/2" copper pipe and a neo that was nearly the same diameter of the pipe- about a 3 foot stick and it took about 14 seconds! AWESOME!
Now to find me a big arse pipe like the one in the vid AND a big arse neo magnet= heaven!

Make kits and sell them on ebay for $10+ if you come across these materials when scrapping. People would love it

I'm thinking that piece of pipe is worth at least $10. Might want to up that price a little...

I just noticed your from NB, LongHairBoy. Nice to see more canucks on here.

Yeah, I don't think you want to drop that big ole piece of Cu tube on your toe :-o

I'm in the middle of cutting up a step van and wondered if this would work on a sheet of aluminum. It does.
