  15. Hello Ldanielrosa Heres is what I understand about Ferrofluids. Ferrofluids are superparamagnetic and have very low hysteresis. The particles are usually iron, magnetite, or cobalt, and are smaller than a magnetic domain, typically 10 nanometers in diameter. The surrounding liquid is typically oil or water (or possibly wax). Surfactants are used to make the suspension more stable, so that the micelle-trapped particles repel each other due to steric hindrance effects. Why would I want to put small particles of stuff inside of my motor? have fun gogo
