How To Make Magnetic Slime

Ferrofluid is more liquid than magnetic slime, so it forms better-defined shapes when exposed to a magnetic field, while silly putty is stiffer than the slime and can crawl slowly toward a magnet All of these projects work best with rare earth magnets rather than iron magnets...

Iron 'jet stream' detected in Earth's outer core

Scientists say Earth's outer core contains a kind of "jet stream" - a fast-flowing river of liquid iron that is surging westwards under Alaska and Siberia...

Magnetic Particles

Magnetic Particles As mentioned previously, the particles that are used for magnetic particle inspection are a key ingredient as they form the indications that alert the inspector to defects Particles start out as tiny milled (a machining process) pieces of iron or iron oxide...

Ferrofluids Magnetic Liquid Iron 60 ml, Ferrofluid, Ferromagnetic Fluid, Liquid Iron, Magnetic Ferrofluid, Ferro Flu Ferrofluids is an amazing liquid which reacts to the influence of a magnetic field...

Magnetic Slime

The magnet is very strong but something prevents the iron filings from leaving the slime and clinging to the magnet The slime holds onto the iron filings by adhesion Adhesion is a force that holds molecules of different substances together In addition to adhesion, the slime polymer is bonded by cohesion...

Magnetic Fluid (Ferrofluid)

Magnetic Fluid (Ferrofluid) Introduction Ferrofluid is a magnetic fluid made out of nanometer sized pieces of iron or various iron oxides, suspended in a liqu The shapes and flow of ferrofluid are surprising and beautiful, and show how magnetic field lines curve around magnetic objects...

What makes the Earth's core so magnetic?

Geologist hypothesize that the core of Earth is composed of a solid iron core and liquid iron outer core Now two things are important about the cores's composition that makes it magnetic: 1 it is composed of iron and 2 it has a liquid outer core As you likely know iron is a magnetic element...

Ferrofluid

A ferrofluid (portmanteau of ferromagnetic and fluid) is a liquid that becomes strongly magnetized in the presence of a magnetic field A grinding process for ferrofluid was invented in 1963 by NASA's Steve Papell as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field...

Will molten iron stick to a magnet?

The loss of magnetism at the Curie temperature applies primarily to "induced magnetism like iron sticking to a magnet" Ferrofluid doesn't really include a molten iron; ferrofluid is a collection of many small but mezoscopic particles, "sawdust", and its magnetism doesn't differ so much from magnetism of normal pieces of iron except that it's easier for the particles to change the orientation...

How Liquid Impacts a Magnet

Simple Science experiment that shows how liquid impacts a magnet , The question answered in this experiment is how does the consistency of a liquid impact magnetic attraction , These materials can also contain iron particles which will make them magnetic and therefore will interfere with your experiment Reply Wally says...

Why Does Earth's Magnetic Field Flip?

Underneath our feet, deep down in the Earth, liquid iron is producing the magnetic field that we all take for granted But every now and then that magnetic field reverses or flips its polarity ....

liquid iron magnetic

See a magnet pull gold and iron out of a liquid - to kicky music! Here's a quick video to satisfy the two loves of everyone with a computer; science and semi-ironic chair dancing Gold and iron oxide particles are suspended in liqu...

How to Make Liquid Magnets

A liquid magnet or ferrofluid is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier When no external magnetic field is present the fluid is not magnetic and the orientation of the magnetite particles is random...
