A rare untouched wet-mesic bottomland hardwood forest in the Mississippi Alluvial Plain, it is the home of several state and national champion trees Carroll Cave: 1977: Camden: private Contains a dendritic system of subsurface karst streams and tributaries. Cupola Pond: 1974: Ripley: federal One of the most ancient sinkhole ponds in the Ozark ...
The elements Dysprosium and Erbium each have two magnetic transitions. They are paramagnetic at room temperature, but become helimagnetic below their respective Néel temperatures, and then become ferromagnetic below their Curie temperatures. The elements Holmium, Terbium, and Thulium display even more complicated magnetic structures. [7]

Molybdenum is a chemical element; it has symbol Mo (from Neo-Latin molybdaenum) and atomic number 42. The name derived from Ancient Greek Μόλυβδος molybdos , meaning lead , since its ores were confused with lead ores. [ 12 ]
Magnetochemistry is concerned with the magnetic properties of chemical compounds and elements. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are ...
A very common source of magnetic field found in nature is a dipole, with a "South pole" and a "North pole", terms dating back to the use of magnets as compasses, interacting with the Earth's magnetic field to indicate North and South on the globe. Since opposite ends of magnets are attracted, the north pole of a magnet is attracted to the south ...
