Ferromagnetism - Georgia State University

Ferromagnetism Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.

May 15, 2020· Earth's magnetic field is generated by molten iron in its outer core. The flow of this liquid iron can influence the location of the planet's magnetic poles. While poles have drifted and even ...

Why does spinning iron cause the Earth's magnetic field ...

I get that moving charges generates magnetic fields. But what makes molten iron charged in the first place? If I melt a chunk of iron into liquid, and slosh it around, do I have now moving charges? The iron in solid state was not electrically charged, why would molten iron be suddenly charged?

Eriez - Trap Magnets

Eriez Permanent Magnetic Traps. Eriez' line of powerful, permanent magnetic Ferrous Traps provide magnetic protection for liquid lines and processing equipment. They preserve product purity by removing small particles of magnetic scale, rust and fine iron contamination.

Ferrofluid in a Bottle: The amazing magnetic liquid

Overview. Ferrofluid is the astonishing liquid that becomes highly magnetized in the presence of a magnetic field. Comprised of nano-scale magnetic particles suspended in a transparent liquid, undisturbed ferrofluid forms into a smooth pool.

Molten Iron Vs. HUGE Magnet - YouTube

Jul 22, 2016· I learned that molten iron is not responsive to a magnetic field until it falls below 1400 fahrenheit, the curie temperature. By then it's solid! PS Check out my video on GoPro's channel!

How to Make Liquid Magnets - ThoughtCo

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.

Is molten iron still attracted to a magnet? : askscience

It is true that liquid iron is not ferromagnetic, but that is because it is above its Curie temperature. Liquid iron is, however, paramagnetic and thus will be weakly attracted to a magnet. Just goes to show that a thousand upvotes does not guarantee a correct answer.

Is Liquid Iron Magnetic? | Naked Science Forum

Will molten iron stick to a magnet? - Physics Stack Exchange

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.

Physics - Molten Metal Magnet

Jan 30, 2007· But Earth's core, a rotating mix of iron and nickel with internal flows driven by the passage of heat, has no battery and no wires. Instead, it creates magnetism by means of self-sustaining feedback. Liquid metal moving through a magnetic field generates a current, similar to that induced in the moving coil of an electric generator.
