Defying Gravity - HUGE Neodymium Magnet vs Copper Tube Experiment - The Power of Lenz's Law!

It's not the size, it's the GAP! Clearance of 1-2mm all-round will slow the magnet way more than 3-4mm. 👍😎 In your last video you can see how a thin plumber's pipe with a small gap to the magnet is MORE effective than a thicker copper pipe with a larger gap.

A furnace made out of a keg?!!! Brilliant!!!

Half the state of Florida wants to know your location right now on account of that chunk of copper...

I use small neodymium magnets in projects all the time and keep a variety of them on hand. People are amazed at the power of a 1/2" disc X 1/4" thick N52 grade magnet when I demonstrate them. And I keep a 1" N52 sphere and a 4' length of 1 1/4" copper water pipe on hand to demonstrate Lenz's law also. Even being familiar with it it never ceases to amaze me at how long it takes to drop through. That 3" magnet you are playing with is a monster. Be vigilant with it especially around the other large magnet. By the time you realize you made a mistake you may have already lost a finger. I've had a 1" magnet bite me pretty good and it happens fast.

i am glade you are being less camera shy and good job with all the videos.

I have seen this Over a thousand times but like a moth to a flame I am ready to see it again

I'm a model railroader and I use neodymium (rare earth) magnets in my open frame (Pittman) motors. It makes a huge difference in current draw and engine performance. Cheers from eastern TN

Really appreciate your efforts, time and expense ..for this experiment. Thanks👍👍

You should try making a simple squirrel cage motor with this setup.

Thanks for including the tube roll/levitation part! Clearly shows how the field acts like a fluid. Well done

3:34, ... I don't know why, but liquid metal has always fascinated me. It's like watching a campfire ... I get the same feeling of wonderment... : )

Idea... Polish you copper tube really well so it will spin on bearings laying down like u shoeed at 8:30 , but power spin the copper tube via belt connected to a motor so the tube spins and plce the magnet inside and see how stable the levitation is

AWESOME I want ANOTHER 20-30 years of LIFE TIME! I am TOO OLD to only be learning this NOW!

Your molds are cracking because the plastic is expanding during the burnout, you can get 3-D printing, filament, specifically for burnouts.

Really? If this is the kind of weird stuff you do…..I’m totally IN!

8:30 Put the copper tube sideways on a rock tumbler, that keeps the tube rotating, so the big metal disc magnet floats in it suspended for as long as the rock tumbler keeps rotating the copper tube.

Next time you should do this, try letting your copper cool naturally instead of quenching it. Your cystaline structure of the copper will be alot different, they will be alot tighter structure. Your eddy currents alot different.

I would have to say you did a very good job of pouring that

Awesome demonstration. Foundry skills galore.

You should make a tall 10 foot clear plexiglass tube that sits on top of the copper. Drop the magnet in the tube see how much it slows it down
