Iron can be found in the Earth's core, in the Earth's crust, in hemoglobin, in steel and in magnets. It is rare to find iron in its elemental form on Earth, but it has been found in igneous rocks in Russia. Iron is a shiny gray metal. When it oxidizes, the resulting compound is known as iron oxide or rust.

أكمل القراءةEquation (14) is the basis for theories of the magnetic susceptibility of individual atoms, ions, or molecules. Langevin diamagnetism Let us now apply these results to a solid composed of ions or atoms with all electronic shells filled. Such atoms have zero spin and orbital angular momentum in its ground state, i.e. 0 S 0 =0 L 0 =0. (16)
أكمل القراءةThe core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.

أكمل القراءةFor fun, we made a rough estimate of what the pull force of an Earth magnet would be, by making a big list of questionable assumptions. If we assume the Earth is a permanent magnet instead of a ball of half-molten iron with electrical currents running through it, we might figure Br max is about 1 gauss. That's a lot weaker than the Br max of 13,200 gauss for a grade N42 magnet …
أكمل القراءةMagnetic field measured on the surface of the Earth is a composite of the main magnetic field generated in the Earth's core and the crustal magnetic field dependent on the magnetization and iron content of the subsurface materials. Hence, magnetic exploration is a powerful tool to detect subsurface magnetic features.

أكمل القراءةYou can picture the iron as pulling field lines into itself. It's true that leaves the field somewhat weaker on the other parts of the magnet face, although in this case it wouldn't be precisely 10% weaker. (I can't do the exact calculation.) It also leaves the field just past the iron, away from the magnet, stronger than it would have been.
أكمل القراءةThe magnet is attracted by the earth's magnetic north pole and always points in that direction. A good way to see how the magnet attracts is to do the following experiment. Take a strong bar magnet and putt a piece of pare over it. Then sprinkle some iron filings on the paper. The iron fillings will make a pattern.
