Amber is sap that oozed long ago from certain softwood trees, such as pine. Over many centuries, it hardened into a semitranspar- ent solid akin to model plastics and ranging in color from yellow to brown. It is a handsome ornamental stone when polished, and sometimes contains the remains of insects that were caught in the sticky sap. Ancient Greeks recognized a strange property of amber. If rubbed vigorously against cloth, it can attract nearby objects, such as bits of straw or grain seeds. Lodestone is a metallic mineral that also has unusual properties. It at- tracts iron. Also, when suspended or floated, a piece of lodestone always turns to one particular position, a north–south direction. The first known written description of the navigational use of lodestone as a compass in Western countries dates from the late twelfth century, but its properties were known even earlier in China. Today, lodestone would be called mag- netized iron ore. 459 3637_CassidyTX_10b 6/14/02 12:47 PM Page 460 460 10.

    8.4 History of the magnetic method in exploration There is little doubt that the Chinese were the first to observe and employ the directional properties of magnetic objects in navigation. They may have invented and used the compass as early as 2600 before the Common Era, but more likely it was as late as 1100 in the Common Era before the compass was used as a navigational instrument. The compass was first noted in Europe around 1200, but the reference by an English monk suggests that the compass had previously been known for an extended period of time. In 1269, P. de Maricourt (P. Peregrinus) investigated the properties of a spherical lodestone. He studied the dipolar nature of magnetic objects and named the poles after the geographic directions that they pointed to (i.e. north and south). He also identified the forces of attraction between unlike poles and the repulsion between like poles. Although the matter was possibly observed earlier by the Chinese and also by Christopher Columbus in his voyages of discovery of the Caribbean Islands in 1492, N. Hartmann in 1510 is credited as the first European to record the declination of the geomagnetic field. In 1544, he was also the first to observe the inclination of the field. Towards the end of the sixteenth century, R. Norman constructed the first inclinometer with the dipping magnetic needle located on a horizontal pivot. With it he was able to show that the inclination of the field corresponds to that on a spherical lodestone, indicating that the cause of the directional component of the compass was within the Earth.

Lodestone is a natural magnet. Photo by: Ryan Somma/Flickr A magnet is made of rock or metal. It can pull some types of metal toward itself. The pulling force of magnets is called magnetism. It is a natural force. What Causes Magnetism? Magnets exist in nature. Certain rocks are magnets. One type of magnetic rock is lodestone. Magnetism is caused by tiny particles. They are called electrons. These particles are found in atoms. Atoms are the building blocks of everything. They are made of electrons and other particles. The electrons rotate around the atom's center. They make tiny magnetic forces. Sometimes many electrons spin in the same direction. Their tiny magnetic forces join together. They make one big magnet. You can use one magnet to make another. You rub the magnet on a piece of metal. You rub in only one direction. This makes the electrons in the metal start spinning. They all spin in the same direction. This is how they make a new magnet. This article is available at 5 reading levels at https://newsela.com. Electricity can also make magnets. It is a form of energy. It is made by flowing electrons. Electricity can be used to make special magnets. They are called electromagnets. Hard And Soft Magnets Some metals make good magnets. One example is nickel. Another is iron. Once they become magnets, they stay magnets.

  • “Mining Magnetite for Your Future.”
    ““MMiinniinngg MMaaggnneettiittee © ffoorr yyoouurr ffuuttuurree..”” What is Magnetite? Magnetite is a valuable source of iron ore and is mainly used in making steel. Magnetite is a ferrimagnetic mineral with definite north and south poles and a chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in discovering and understanding plate tectonics. The relationships between magnetite and other iron-rich oxide minerals such as ilmenite, hematite, and ulvospinel have been much studied, as the complicated reactions between these minerals and oxygen influence how and when magnetite preserves records of the Earth's magnetic field. Magnetite has been very important in understanding the conditions under which rocks form and evolve. Magnetite reacts with oxygen to produce hematite. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks. Magnetite also occurs in many sedimentary rocks, including banded iron formations. In many igneous rocks, magnetite-rich and ilmenite-rich grains occur that precipitated together from magma. Magnetite also is produced from peridotites and dunites by serpentinization. The chemical IUPAC name is iron(II,III) oxide and the common chemical name ferrous-ferric oxide. The formula for magnetite may also be written as FeO·Fe2O3, which is one part wüstite (FeO) and one part hematite (Fe2O3).
