Why Magnetite is Magnetic by Maia Warner on Prezi By, Maia Warner Why is Magnetite Magnetic? Why is Magnetite Magnetic? There's the idea that there was a Shepard boy named Magnes who discovered Magnetite in Macedonia when he was pasturing his flock of sheep on mount Ida, and the Magnetite clung to the metal nails in his shoes and the metal end of his crook...
Ferromagnetism - HyperPhysics Concepts 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...
MAGNETIC FIELDS - nde-edorg Each tiny magnetic iron filing is a tiny magnet with a north and south pole, just like a tiny compass When the iron filings are sprinkled, those very close to the magnet, where the magnetic force is the strongest, will cling to the magnet...
Magnetite - Wikipedia Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself It is the most magnetic of all the naturally-occurring minerals on Earth Naturally-magnetized pieces of magnetite, ,...
Why is iron a magnetic metal but aluminum is not? [Solved] The question of a material being magnetic or not is very difficult, as there are many physical scenarios leading to magnetism The popular understanding of a magnetic material is ferromagnetism ....
Fun Magnet Facts for Kids - Magnetic Information , Magnetic objects must be inside the magnetic field to respond, which is why you may have to move a magnet closer for it to have an effect The Earth's core is believed to be a mix (alloy) of iron and nickel, giving the Earth its own magnetic field...

What causes the Earth's magnetic field?| Explore | , This flow of liquid iron generates electric currents, which in turn produce magnetic fields Charged metals passing through these fields go on to create electric currents of their own, and so the cycle continu...
Re: Why is austenitic iron non-magnetic, but ferritic iron , But when you apply an external magnetic field to a piece of iron, the zones that are aligned with the field grow and the ones that are not shrink This causes a net magnetic field in the iron, and the iron piece is attracted to the magnet...

Magnet - Wikipedia A magnet is a material or object that produces a magnetic fieldThis magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field...
Get the Iron out--of Your Breakfast Cereal - Scientific , Like many metals, iron is magnetic, so if you have a strong enough magnet, you will be able to pick it up Will you be able to pick up your box of breakfast cereal just by magnetic force alone?...
Iron - University of Denver A property of the iron family for which there is no substitute at an equivalent cost is that they can be induced to provide a strong magnetic field with only small excitation by an electric current It is a very remarkable property, so an effort will be made to explain how it arises, and how it is used...
Magnetism - Wikipedia Each atom of iron has an unpaired electron whose spin can be lined up to that of the unpaired electron from a neighboring iron atom The spinning of the charged electron creates a magnetic moment, which in turn can align with an external magnet, thus making iron magnetic...
Factors Determining Magnetic Properties by Ron , Factors Determining Magnetic Properti by Ron Kurtus (revised 15 February 2016) There are three main factors that determine the magnetic properties of a material The most basic factor is the configuration of the electrons in the material's atoms...
Not All Iron Is Magnetic - ThoughtCo The a allotrope is magnetic, yet when the temperature increases so that the a form changes to the b form, the magnetism disappears even though the lattice doesn't change On a related note, iron isn't the only metal to display magnetism...
chp 24 h/w Flashcards | Quizlet The magnetic fields of individual iron atoms are strong enough to align the magnetic fields of neighbor atoms The atoms in wood have much weaker magnetic fields Why will dropping an iron magnet on a concrete sidewalk make it a weaker magnet?...
Iron - Wikipedia Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26 It is a metal in the first transition seriIt is by mass the most common element on Earth, forming much of Earth's outer and inner coreIt is the fourth most common element in the Earth's crustIts abundance in rocky planets like Earth is due to its abundant ,...
Manganese has more unpaired electrons than Iron so why is , The magnetic moments of such magnetic atoms are oriented randomly and their magnetic moments cancel out each other and no permanent magnet But by applying an external magnetic field the magnetic moments are oriented in the same direction with the applied field so the outcome field from the material is larger than the applied...
Paramagnetic Properties of Fe, Fe 2+, and Fe 3+ Elemental iron and iron (III) are paramagnetic because of the necessity of unpaired electrons in their orbitals Iron (II) is also in this same position most of the time When iron (II) is bonded to certain ligands, however, the resulting compound may be diamagnetic because of the creation of a low-spin situation...
Iron Oxide Nanoparticles, Characteristics and Applications , Iron oxide (IO) nanoparticles consist of maghemite (γ-Fe2O3) and/or magnetite (Fe3O4) particles with diameters ranging from 1 and 100 nanometer and find applications in magnetic data storage, biosensing, drug-delivery etc...
