Magnetite - an overview | ScienceDirect Topics

Magnetite is widely distributed usually with octahedral, or spherical, morphology, in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumerolic deposits, and in living forms. For the latter the mineral plays some very important role, which we highlight in Section 8.04.3.3.2.

Heme Iron Vs. Nonheme Iron: What's the Difference?

Jul 11, 2017 · Heme iron is the type of iron found in blood and muscle. Present in animal foods like red meats, fish, and poultry, heme iron is a significant source of the absorbed iron in a typical western diet, though it only makes up about one-third of dietary iron. Heme iron gets its name from the heme protein attached to a lone iron atom.

Magnetite - Wikipedia

Magnetite differs from most other iron oxides in that it contains both divalent and trivalent iron. [9] As a member of the spinel group, magnetite can form solid solutions with similarly structured minerals, including ulvospinel (Fe 2 TiO 4 ), hercynite (FeAl 2 O 4 ) and chromite (FeCr 2 O 4 ).

Halbach array - Wikipedia

A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets can be continued indefinitely and have the same effect. The effect of this arrangement is roughly similar to many horseshoe magnets .
