But Seriously -- How The F*** Do They Work?: Stack Of Magnets "Float" Down A Copper Pipe
This is a video of a stack of neodymium magnets 'floating' down a length of copper pipe. I watched it like ten times while trying to brainstorm a functional hoverboard design with no luck. Dammit Marty, you've ridden one -- how the f*** do they work?! "Not on water." God you're no help.
The neodymium magnets are super powerful and even though they are not attracted to the copper, they still produce eddy currents that buffer the fall as seen in the video. Lenz's Law make a great experiment for kids to adult. Also, great at parties when conversation goes stale.
You know what else is great at parties when the conversation goes stale? Stealing as much beer as you can and getting the f*** out. That or spin the bottle. But we are NOT using my ship in a bottle again -- you broke the sails spinning too hard last time.
Hit the jump for the worthwhile magnet magic in action.
Thanks to Trina and little bear, who've both swallowed magnets before and claim they caused iron deficiencies. Hey I believe it.
