What makes iron magnetic? | Yahoo Answers

2008-12-2 · This ferromagnetism and its partially-filled shells create what are called magnetic domains. All of those little domains just sitting in that iron lump point hither and yon, totally randomly, and therefore just "cancel each other out," meaning that your lump of iron has no real magnetic field (there is an almost imperceptibly small, tiny one).

Magnetite - Wikipedia

2021-1-1 · Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It 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, called lodestone, will attract small pieces ...

Phosphate selective recovery by magnetic iron oxide ...

If a magnetic iron oxide such as magnetite (Fe 3 O 4) or maghemite (γ-Fe 2 O 3) is used, the iron oxide impregnated materials can be rapidly separated by application of an external magnetic field, thereby enabling the efficient recovery of the adsorbed P (Fang et al. 2017, Wu et al. 2017).

Why is iron magnetic, unlike other metals? - News ...

2020-12-25 · In other words, they behave in a 'magnetic' way. Only a few elements, including iron, can hold on to this magnetization when the magnet is removed. Such a magnetization is called a spontaneous or remanent magnetization. Nickel, cobalt and gadolinium Iron is not the only material capable of possessing a remanent magnetization.

Ferromagnetism - Georgia State University

2018-10-17 · 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.

Magnetic materials - Boston University Physics

2004-12-31 · Hard iron is used in permanent magnets. To make a permanent magnet, a piece of hard iron is placed in a magnetic field. The domains align with the field, and retain a good deal of that alignment when the field is removed, resulting in a magnet. An electromagnet, in contrast, uses soft iron; this allows the field to be turned on and off.
