Can Ferrofluid Be Used as a Lubricant for Magnets and PVC Pipes?

AI Thread Summary
Ferrofluid can theoretically be used as a lubricant between a neodymium magnet and a PVC pipe, but concerns about abrasion from the magnetic particles exist. Traditional oil lubricants are readily available and may be more effective for reducing friction without the risks associated with ferrofluid. The discussion also humorously touches on the unconventional idea of using ferrofluid in a high-tech context, likening it to a "high-tech condom." Overall, while ferrofluid has potential, its practicality and safety as a lubricant in this scenario are questionable. The conversation highlights the importance of considering long-term effects and alternative options for lubrication.

can I use ferrolfluid as a lubricant between a cylindrical neodymium magnet and a pvc pipe that the magnet fits snugly in(still will move back and forth in the pipe but does experience a little friction)?

Why would you want to? Realize that "ferrofluid" is a suspension of magnetic particles in oil, and that we have a simple version for lubrication called "oil" that you can get in pretty much any viscosity that you want.
 
I should imagine that the ferromagnetic particles in the fluid could cause abrasion. This could be relevant in the long term.
 
Am I the only one here who is thinking "high-tech condom"?
 
That's a different sort of attraction.

What! No, wait a minute here! That is so totally not true! It wouldn't count anyhow, because I was drunk. Besides, you can't believe anything that damned muskrat says; she'd do anything for half a gram.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
