SCIENCE GIZMOS: Ferrofluid | 100ml | Excellent scientific demonstration

$ 73.20 excl. GST

This science gizmo 100ml Ferrofluid comprises of nanosized particles ( >10 nanometers) of magnetite, hematite and other compounds containing iron in a carrier fluid.
When polarised near a magnetic field, it produces some incredible liquid formations.

“Demonstrate magnetic fields in an incredible way!
A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field.
This bulk fluid is available separately from our kits, for people who already know how to use it, or need a little extra for their experiments.

Notice: While Ferrofluid is amazing, it is also very messy stuff. Rubber gloves, safety goggles, and protective clothing should be used. Close adult supervision required”

The Ferrofluid in the display cells is not the same as the bulk Ferrofluid. Bulk Ferrofluid cannot be used to make a display cell.
Our Ferrofluids are intended for educational and demonstration purposes only.
They are not designed for use in loudspeakers or any other device. Sorry, we do not carry any Ferrofluids designed for such purposes

Wikipedia info
[Wikipedia excerpt:  ‘… Ferrofluid is a liquid that is attracted to the poles of a magnet. They are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of tiny nanoparticles is weak enough that the surfactant’s Van der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually do not retain magnetization in the absence of an externally applied field and thus are often classified as “superparamagnets” rather than ferromagnets….’ ].
