A metal (Ancient Greek métallon, μέταλλον) is an element, compound, or alloy characterized by high electrical conductivity

Metals are usually inclined to form cations through electron loss,[1] reacting with oxygen in the air to form oxides over changing timescales (iron rusts over years, while potassium burns in seconds). Examples: 4 Na + O2 → 2 Na2O (sodium oxide)2 Ca + O2 → 2 CaO (calcium oxide)4 Al + 3 O2 → 2 Al2O3 (aluminum oxideMetals are often extracted from the Earth by means of mining, resulting in ores that are relatively rich sources of the requisite elements. Ore is located by prospecting techniques, followed by the exploration and examination of deposits. Mineral sources are generally divided into surface mines, which are mined by excavation using heavy equipment, and subsurface mines.

Once the ore is mined, the metals must be extracted, usually by chemical or electrolytic reduction. Pyrometallurgy uses high temperatures to convert ore into raw metals, while hydrometallurgy employs aqueous chemistry for the same purpose. The methods used depend on the metal and their contaminants. When a metal ore is an ionic compound of that metal and a non-metal, the ore must usually be smelted - heated with a reducing agent - to extract the pure metal. Many common metals, such as iron, are smelted using carbon as a reducing agent. Some metals, such as aluminum and sodium, have no commercially practical reducing agent, and are extracted using electrolysis instead. Sulfide ores are not reduced directly to the metal but are roasted in air to convert them to oxides.

Does magnetic paint on a wall cause problems for computers in the room?

No, magnetic paint just allows magnets to stick to the paint, it is not magnetic itself. Even if it was, it would be much too weak to cause any damage.

What is magnetic paint?

Magnetic paint is just like regular latex paint, except for the fine particles of iron dust mixed throughout which gives it a special magnetic quality. When applied to a surface, you end up with a layer of primer with many tiny flecks of iron spread throughout. Magnets are attracted to these flecks of iron transforming your project into a magnetic surface.


If you cover magnetic paint with fabric is it still magnetic?

Yes. The proximity of fabric doesn't change the magnetic properties of magnetic paint. Umm... the paint will still be magnetic even if you bury it in the desert where nobody will find it. However, depending on the thickness of the fabric, it may not noticably attract ferrous objects any longer! Try experimenting with thin fabrics like nylon or silk and then slightly thicker fabrics -- to find how thick the fabric can be to still permit the paint to act as a magnet for your purposes.

What is an magnetic domain made up of?

A magnetic domain is made up of a group of atoms with aligned magnetic moments. These aligned magnetic moments create a magnetic field within the domain, which contributes to the overall magnetic properties of the material.
