What is Paleomagnetism? Rating Newest Oldest. Best Answer: Paleomagnetism is the earth's magnetic field as it existed in the past. The magnetic field present in fossilized rocks, created by the earth's magnetic field when the rocks were formed. http://education.yahoo.com/reference/dic...

Ferrimagnetism In physics, a ferrimagnetic material is one that has populations of atoms with opposing magnetic moments, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains. This happens when the populations consist of different materials or ions. Ferrimagnetism is exhibited by ferrites and magnetic garnets. The oldest known magnetic substance, magnetite, is a ferrimagnet; it was originally classified as a ferromagnet ...

About Rare-Earth Magnets The rare-earth magnets currently available at the retail level are made of neodymium iron boron (NdFeB). Only three elements are ferromagnetic at room temperature; these are iron, cobalt and nickel. Virtually all other elements increase permanence (coercivity), but any magnet must contain one of the base three to work.

paleomagnetism (pā'lē-ō-māg'nĭ-tĭz'əm) The fixed orientation of a rock's magnetic minerals as originally aligned at the time of the rock's formation. Paleomagnetism is usually the result of thermoremanent magnetization (magnetization that occurs in igneous rocks as they cool). Examination of the paleomagnetism of the Earth's ocean floors revolutionized the field of geology by providing evidence for the existence and movement of tectonic plates.

- Magnetism is the phenomenon associated with the motion of electric charges, although the study of magnets was very confused before the 19th century because of the existence of ferromagnets, substances such as iron bar magnets which maintain a magnetic field where no obvious electric current is present (see below).

Scientists Generate Magnetic Field by Using Heat Instead of Electricity In theory, it is also possible to generate a magnetic field by using a temperature difference across an electrical insulator (‘thermomagnetism’). This has been referred to as the Magnetic Seebeck effect, and has enormous applications for future electronics such as solid-state devices and magnetic-tunnel transistors.

- Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel.

Rare-earth magnet Rare-earth magnets are strong permanent magnets made from alloys of rare earth elements. Developed in the 1970s and '80s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.owever, they form compounds with the transition metals such as iron, nickel, and cobalt, and some of these have Curie temperatures well above room temperature. Rare earth magnets are made from these compounds.

Geology Exam 1 Paleomagnetic inclination can be used to determine the ancient latitude of a continent by the curving line that came to be known as an apparent wander path. The paths allowed geologists to see how the continents moved relative to a fixed pole. What are marine magnetic anomalies? Marine magnetic anomalies are the difference between the expected strength of earth's main dipole field at a certain location and the actual measure strength of the magnetic field at that location.

Ferromagnetism This is the magnetic arrangement found for the elemental metals iron (Fe), nickel (Ni), and cobalt (Co) and for their alloys with one another and with some other elements. These materials still constitute the largest group of ferromagnets commonly used.

Ferrimagnetism In physics, a ferrimagnetic material is one that has populations of atoms with opposing magnetic moments, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains.errimagnetism can also occur in molecular magnets. A classic example is a dodecanuclear manganese molecule with an effective spin of S = 10 derived from antiferromagnetic interaction on Mn(IV) metal centres with Mn(III) and Mn(II) metal centres.

Paleomagnetism Paleomagnetism (or Palaeomagnetism in the United Kingdom) is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials.Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form.pparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading. Paleomagnetism continues to extend the history of plate tectonics back in time and are applied to the movement of continental fragments, or terranes.

- Easily magnetized dysprosium compounds can be used in data storage applications such as hard drives, and dysprosium is often used to substitute for some of the neodymium in neodymium-iron-boron magnets. Substituting these high-powered magnets with dysprosium increases their corrosion resistance and coercivity.
