Magnetic Ferrofluid

Ferrofluid improves sound quality in audio equipment.

Ferrofluids have the ability to absorb or buffer mechanical vibration and are used to improve audio quality in sound recording equipment or to absorb and dissipate heat in loudspeaker cones and voice coils. Ferrofluid liquid can also improve the operation of mechanical devices by creating a frictionless,semi-viscous seal for rotating shafts in computer hard drives and other high-performance equipment. Ferrofluid creates a dust-free environment that lowers operating temperatures, reduces wear and tear and prolongs the life of these advanced types of computerised equipment.

Ferrofluid has medical applications.

Ferrofluid contrasting agents placed into human tissue can enhance the image quality and definition delivered by Magnetic Resonance Imaging machines. Ferrofluid helps these technologies to more accurately reflect the extent of bone or tissue damage. Experiments with the delivery of localised medicines to areas of the human body that can be targeted and controlled remotely by magnets are currently being investigated by medical researchers.

Ferrofluid helps us to understand magnetism.

Ferrofluid liquid is an excellent educational tool that helps demonstrate visually the otherwise invisible path of magnetic fields as they flow between the North and South poles of a magnet. Frenergy stocks EFH1 Ferrofluid in quantities from 30 to 120µL and also stocks a practical and comprehensive educational kit that includes magnets and everything else you need to conduct your own Ferrofluid experiments. Browse the Alnico Magnet category to find other Frenergy educational products. Orders over $50 are shipped free Australia wide. See the shipping and returns terms and conditions in the FAQ pages.

Frequently Asked Question

What to do with ferrofluid?
Ferrofluids perform in a similar way to traditional iron filings and can be used as an educational tool in schools and universities. The viscous fluid has similar properties to the metal filings but has additional highly technical applications in advanced scientific technologies and aerospace industries.

Where can I buy ferrofluid?
Buy Ferrofluid products via the Frenergy website. Secure payment and free or fast Australia wide shipping options are available. Contact our team via email for help and advice on Ferrofluid products and get a prompt reply using the customer contact form.

What is ferrofluid made of?
As its name suggests, Ferrofluid contains ferrous nanoparticles of magnetite which are suspended in the viscous liquid. Ferrofluid liquid is not itself magnetic but instead reacts to the presence of a magnetic field and is attracted to it.
