magnetic mineral उदाहरण वाक्य

To relate magnetic measurements to the environment, environmental magnetists have identified a variety of processes that give rise to each magnetic mineral.
Some models are able to reject highly magnetic minerals, like iron, that are simply part of the soil, which foiled the older machines.
Plots of against are widely used in rock magnetism as a measure of the domain state ( single-domain or multidomain ) in magnetic minerals.
The past magnetic field is recorded mostly by strongly magnetic minerals, particularly iron oxides such as magnetite, that can carry a permanent magnetic moment.
Local environments may contain magnetic mineral deposits and artificial sources such as MRIs, large iron or steel bodies, electrical engines or strong permanent magnets.

Basalt the iron-rich, volcanic rock making up the ocean floor contains a strongly magnetic mineral ( magnetite ) and can locally distort compass readings.
For volcanic rocks, magnetic minerals, which form in the melt, orient themselves with the ambient magnetic field, and are fixed in place upon crystallization of the lava.
This is often indicated by a rock with a surface which is dark and has a metallic luster, not all magnetic mineral bearing rocks have this indication.
Iron can be obtained on the Earth's surface from meteorites; the mineral lodestone is rich in the magnetic mineral magnetite and can be magnetized by a lightning strike.
Some such minerals may have a significant positive magnetic susceptibility, for example serpentine, but this is because the minerals have inclusions containing strongly magnetic minerals such as magnetite.
