SUMMARY

Ferrofluid, a suspension of magnetic particles in oil, is not recommended as a lubricant between neodymium magnets and PVC pipes due to potential abrasion from the ferromagnetic particles. While it may reduce friction temporarily, the long-term effects could lead to damage. Traditional lubricants, such as oil, are more suitable for this application, offering a range of viscosities without the risks associated with ferrofluid. Users should consider the implications of using high-tech materials in simple mechanical applications.

PREREQUISITES
  • Understanding of ferrofluid properties and composition
  • Knowledge of neodymium magnets and their applications
  • Familiarity with lubrication principles and oil types
  • Basic mechanics of friction in cylindrical systems
NEXT STEPS
  • Research the properties and applications of ferrofluids in engineering
  • Explore the effects of different lubricants on friction in mechanical systems
  • Investigate alternative high-tech lubricants suitable for magnets
  • Learn about the long-term effects of using unconventional lubricants
USEFUL FOR

Engineers, material scientists, and hobbyists interested in magnet applications and lubrication technology will benefit from this discussion.

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.
