Magnetite crystals with a cubic habit are rare but have been found at Balmat, St. Lawrence County, New York, [47] [48] and at Långban, Sweden. [49] This habit may be a result of crystallization in the presence of cations such as zinc. [50] Magnetite can also be found in fossils due to biomineralization and are referred to as magnetofossils.

A large drive-in RF anechoic test chamber. Note the orange caution cones for size reference. Pyramid RAM. The grey paint helps to protect the delicate radiation-absorbent material. One of the most effective types of RAM comprises arrays of pyramid-shaped pieces, each of which is constructed from a suitably lossy material. To work effectively ...
Maghemite forms by weathering or low-temperature oxidation of spinels containing iron(II) such as magnetite or titanomagnetite. Maghemite can also form through dehydration and transformation of certain iron oxyhydroxide minerals, such as lepidocrocite and ferrihydrite.
is the average magnetic path length = 0.94 (constant value) m {\displaystyle m~} is the mass of the sample in kilograms If all conditions are as defined in the standard, the standard deviation of the reproducibility of the values is not greater than 1.5% up to 1.5 T [ clarification needed ] for non-oriented electrical steel and up to 1.7 T for ...
Magnetic strips and EMV chips can sustain damage from being scratched, for example, by a key or coin. These scratches can make it difficult for card readers to pick up the information on the ...
Emery is a granular rock used to make an abrasive powder. It largely consists of corundum (aluminium oxide), mixed with other minerals such as the iron-bearing spinels, hercynite, and magnetite, and also rutile . Industrial emery may contain a variety of other minerals and synthetic compounds such as magnesia, mullite, and silica.

Test on a small, inconspicuous area first. Using light pressure, work in small sections, starting with the rubber soles. For canvas or leather portions, use extra-gentle pressure to avoid damage.
