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.
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.

Owner Response:Jon, thank you for mentioning the lack of information on our website. We have included more detail for the customer that includes the need for eye and clothing protection. This liquid will color skin if touched and does not wash off easily. The warning not to bring a magnet close the the ferrofluid is simply because the fluid will jump to the magnet and you will not be able to remove it once it's "stuck" on the magnet. The proper way to use this product is with a bolt or nut that has a magnet attached with a small pie tin between the two. This liquid has amazing properties but requires care in its use.
Great eye catching display.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s) MS-ESS2-2
| Elementary || || Middle School || || High School |
Students will benefit from demonstrations using Ferrofluid. Ferrofluid can be quite messy if handled recklessly. This kit is recommended for hands-on use with students in middle school and older.
| || MS-PS1-3 |
Students can use Ferrofluid to gather and make sense of information during an investigation. MS-PS2-3
Students can use the Ferrofluid in an investigation to ask questions about data to determine the factors that affect the strength of magnetic forces. MS-PS2-5
Students can use the Ferrofluid to conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact. MS-ESS2-2
Students can do an activity with the Ferrofluid with a Bar Magnet to construct an explanation based on evidence for how geoscience's processes have changed Earth's surface at varying time and spatial scales.
| || HS-PS3-5 |
The Ferrofluid can be used to develop and model how two objects interacting through magnetic fields, illustrates the forces between objects and the changes in energy of the objects due to the interaction.
Using a variety of magnet shapes and the Ferrofluid will allow students to observe the various shapes magnetic field can take.
When a bar magnet is used, it can model how the magnetic properties of the North and South Poles of the Earth. Students can use this information to model how, over the course of Earth's history, the magnetic field of the poles have swapped location, based on magnetic readings of the Atlantic Ocean floor. Rotate the magnet 180 degrees to model the geologic history of the Earth's magnetic field. DCI/PS1.A
Each pure substance has characteristic physical and chemical properties that can be used to identify it. DCI-HS/PS2.B
Investigations using Ferrofluid and magnets will demonstrate the attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects. Use the Ferromagnetic Liquid to show the magnetic field. S&E
Students can use the Ferrofluid to develop a model to describe a phenomenon. The students will be engaged in learning as they visualize various magnetic fields.
