Are there any magnetic liquids?
Magnets as we know them are always solid, but the closest thing we have to a magnetic liquid is a class of liquids called ferrofluids. Made up of iron-oxide particles suspended in liquids, these materials are only magnetic temporarily, when exposed to other magnets.
Are ferrofluids expensive?
There are generally two ways you can make ferrofluid. The more expensive way (around $100 per cartridge of magnetic primer toner and some vegetable oil), and the cheaper way which is a little more difficult to make, but will only cost you about $10.
What are ferrofluids used for?
Ferrofluid is used in rotary seals in computer hard drives and other rotating shaft motors, and in loudspeakers to dampen vibrations. In medicine, ferrofluid is used as a contrast agent for magnetic resonance imaging (MRI).

Can a magnet be in liquid form?
However, it is possible to “magnetize” ordinary liquids by dispersing into them very fine magnetic particles. The resulting liquid becomes a homogeneous magnetic material, just like a solid, but it retains its fluid characteristics.
Can you touch ferrofluid?
Can you touch ferrofluid? You most certainly can but it is not recommended. Ferrofluids are considered a major skin irritant. Once you contact the ferrofluid with your finger, the liquid quickly begins to travel up the ridges of your finger and around your nail.
Can you make your own ferrofluid?
Pour a bit of vegetable oil into a shallow dish, just enough to make a thin film across the bottom. Pour iron filings into the oil and mix the two until they have become a thick, sludge-like material. This is your ferrofluid! Removing the magnetic field will allow the ferrofluid to flow like a liquid again.
Can a magnet attract liquid?
Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid 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.
Is ferrofluid safe to touch?
How are magnetic ferrofluids used in everyday life?
1 Steve Papell of NASA developed the fluid in the 1960’s in response to the need for moving fuel in space where there is no gravity 3 They do not retain any magnetization once the external magnetic field is removed. 4 Ferrofluids have strong staining capacity. They can stain skin, glasses, bathroom sinks etc. Be careful when you use them.
How to preserve a bottle of ferrofluid fluid?
This bottle is well worth the price and had enough fluid to make 3 decorative ferrofluid jars, with some leftover. To preserve and display the ferrofluid, I coated a glass jar with Scotchguard then filled it with vodka and added a tablespoon or so of ferrofluid, then sealed the jar.
Is it safe to drill neodymium magnets?
• Magnetized materials are REGULATED FOR AIR TRANSPORT and are considered a HAZARDOUS MATERIAL. • Neodymium magnets will lose their magnetic properties if heated above 175°F (80° C). • Do Not cut or drill Neodymium Magnets, there is a both a fire and fracture hazard and the dust is toxic.
