The Thing Posted December 19, 2005 Share Posted December 19, 2005 Okay, I posted this in the physics section but got no replies whatsoever. Perhaps it is better here: can a mod delete the post in the physics section? It has the same title. So, MagnaView Fluid, How frictionless is that thing? If I were to push a magnet covered in magnaview fluid in a plastic tube, would the friction between the fluid and the tube be greater or smaller than the friction between the magnet and the air if I were to push a levitated magnet? Is it possible to create a sort of "magnaview train" and push it and accelerate it using magnets? I'm planning on doing an experiment on this...

The Thing Posted December 20, 2005 Author Share Posted December 20, 2005 Okay... no response... MagnaView Fluid=Ferrofuid Helps anyone? Link to comment Share on other sites More sharing options...
rthmjohn Posted December 20, 2005 Share Posted December 20, 2005 Did you read the unitednuclear page thoroughly? It says the magnet would be near frictionless. I'm pretty sure the friction between the fluid and tube would be greater, but I could be wrong. Link to comment Share on other sites More sharing options...
Lance Posted December 20, 2005 Share Posted December 20, 2005 The ferrofluid would have much more friction. Link to comment Share on other sites More sharing options...
xeluc Posted December 20, 2005 Share Posted December 20, 2005 Think of it like this. Does a boat or an airplane experience more friction.... Link to comment Share on other sites More sharing options...
The Thing Posted December 21, 2005 Author Share Posted December 21, 2005 You tell me There goes my idea of the Ferrofluid train down the drain <--- W00t! I'm a rapper w/ m4d sk1llz0rz OMFG! Seriously, is there any application of the near frictionlessness property of ferrofluid beyond that of lubricating bearings? Is it more frictionless than, say, machine oil? Thanks.

chemfreak Posted December 27, 2005 Share Posted December 27, 2005 on the note of frictionless things cant liquid helium crawl out of jars if so @ wat temp(F please) Link to comment Share on other sites More sharing options...
jdurg Posted December 27, 2005 Share Posted December 27, 2005 Yes, liquid helium shows virtually no effects of friction. However, helium is only a liquid a few degrees above absolute zero (-273 C, or about -459 degrees Fahrenheit). (BTW, while this sounds very nit-picky and anal-retentive, please try to fully spell out your words when you type. When people see posts filled with 'wat' instead of 'what', 'fo' instead of 'for', 'wit' instead of 'with', or various other slang terms they are less likely to take your posts seriously and much less likely to respond to them. I'm just stating that to help you out here. ) Link to comment Share on other sites More sharing options...
calbiterol Posted December 27, 2005 Share Posted December 27, 2005 Plus, there's a lot of people here who don't speak English as a native language, and spelling out your words completely makes it infinitely easier on the people who aren't as fluent with their English.
