Magnetic Hematite Vs. Hematite Mineralogy Geology | eHow

(99+ مراجعات العملاء)

True hematite, though ironcontaining, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite (the artificial material). Like true hematite, magnetite is also an iron oxide, but its iron atoms are arranged in a manner that make it magnetic ...

Why is Earth's Core Iron?

(99+ مراجعات العملاء)

 · Not too sure of the magnetic properties of iron versus nickel. As said in another answer, there is simply much more iron around than nickel. But the earth has also a large amount of other metals: silicon, magnesium, calcium, aluminium. So why is the core made of ironnickel and not the other stuff? The answer is in the oxygen.

Core/shell iron/iron oxide nanoparticles: are they ...

(99+ مراجعات العملاء)

 · Core/shell iron/iron oxide nanoparticles have been proposed as a promising system for biomedical appliions, because they combine a core (iron) with a high magnetic moment and a shell (iron oxide) with good biocompatibility. However, due to the interdiffusion of atoms between the core and the shell, with increasing time the core progressively shrinks until the particles eventually become ...

 · Rust (a collection of some iron oxides: ) is virtually nonmagnetic, unlike plain iron or most types of steel. If the sheet metal on your car has really rusted through, there will be almost no magnetic force between it and the magnetized screwdriver. It sounds like those spots should be patched, since that's not just a thin surface layer of rust. Mike W. (published on 09/15/2011) Followup on ...

 · Sedimentary deposits are represented by the lean siliceous ore of the iron formation, as at Moose Mountain and Temagami, Ontario, and by magnetic black sand found on the north shore of the St. Lawrence; both of these may prove to be important. They can be concentrated magnetically, and this is being done on a large scale with the taconite of Minnesota, the ore carrying only 25% of iron. The ...

Laminated magnetic cores are made of stacks of thin iron sheets coated with an insulated layer, which lie parallel to the lines of flux. These insulation layers serve as barriers to prevent eddy current so that it can flow only through the narrow loops within each single lamination layer. This technique prevents major of the current from flowing and reduces eddy current to a very low level ...
