Is Silver Magnetic? Silver isn't noticeably magnetic. In fact, only iron, nickel, cobalt, gadolinium, neodymium and samarium are magnetic in our everyday lives.
Q & A: Hematite Magnets | Department of Physics .
Anyway, although hematite is weakly magnetic (and hence can be attracted to your magnet), its magnetism is "soft", meaning that its domains don't stay lined up when the magnetic field is removed. In fact, the magnetic forces between the domains tend to make them line up opposite to each other. Some impurities in hematite can raise the strength of magnetization of its .
How is gold made? - UCSB Science Line
How is gold made? Question Date: 2002-10-01: Answer 1: . Gold, in its pure form is not made - it occurs naturally in an elemental form. On a side note, the history of alchemy was largely based on the desire of people (probably kings!) to combine other (cheap and abundant) elements and compounds to make gold. Most of the "gold" products such .
Magnetic Hematite Vs. Hematite Mineralogy Geology | eHow

How magnet is made - material, manufacture, making .
The iron ore magnetite, also known as lodestone, is a natural permanent magnet. Other permanent magnets can be made by subjecting certain materials to a magnetic force. When the force is removed, these materials retain their own magnetic properties. Although the magnetic properties may change over time or at elevated temperatures, .
Titanium - Wikipedia
Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.
Magnetite is the most magnetic mineral. High iron content gives magnetite its opaqueness and black color. Spinel which shares the same structure is variably colored and transparent because it contains magnesium and aluminum instead or iron. Magnetite is dense (specific gravity 5.20) mineral. This is considerably above common silicate .
University of Minnesota's Mineral Pages: Calcite
Many people assume that magnetite's name is derived from its magnetic properties, but the term 'magnet' actually comes from the mineral. 'Magnetite' was named after the Magnesia region of Thessaly, Greece, the home of the Magnetes and an important center of iron production. The historical importance of this region's mineral deposits is .
Meteorite Home Tests
Iron ore is the most common meteor-wrong. Magnetite especially is very magnetic (hence its name) and hematite may or may not be mildly magnetic.
Compass - Wikipedia
The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field.The magnetic field exerts a torque on the needle, pulling the North end or pole of the needle approximately toward the Earth's North magnetic .
Magnet - Wikipedia
A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic .
Ore – Official Minecraft Wiki
Usage . Ores are primarily collected for crafting purposes, such as for tools and armor.Redstone is obtained from redstone ore, which can be used to create redstone circuits.Ore can also be combined to create a block of the material's type. Obtaining resources from ores is as simple as mining them (this is not the case for iron and gold ores.

Magnetite - Wikipedia
Magnetite is a rock mineral and one of the main iron ores.With the chemical formula Fe 3 O 4, it is one of the oxides of iron.Magnetite is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of .
Magnetism, Magnetic Flux and Magnetic Materials
A small magnetic field is created around the conductor with the direction of this magnetic field with regards to its "North" and "South" poles being determined by the direction of the current flowing through the conductor.
Copper - Wikipedia
Copper is one of the few metals that occur in nature in directly usable metallic form (native metals) as opposed to needing extraction from an ore.This led to very early human use, from c. 8000 BC. It was the first metal to be smelted from its ore, c. 5000 BC, the first metal to be cast into a shape in a mold, c. 4000 BC and the first metal to be .
