a list of magnetic metals

Magnetic ores like pyrolusite (MnO 2 ) and chromite (FeO.Cr 2 O 3 ) are enriched by this method by making use of the difference in the magnetic properties of the ore and gangue particles. ..

By the study if electronic configuration of transition metals it is understood that they generally contain one or more unpaired electrons in the (n-1)d orbital. Due to these unpaired electrons they behave as paramagnetic substances. These substances are attracted by the magnetic..

A completely satisfactory theory of magnetism has still not been formulated. At present it is assumed that magnetism is due to the movement of the electrons. The electrons circulate around the nucleus of the atom. They also spin around an axis through their centres. These two mo..

The Earth's Magnetism - A magnetic compass was used to help the sailors for navigational purpose. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magnetic field. Will..

Metals and Non-metals..

Summary - Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point. Electrical potential is a scalar quantity. The potential di..

Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease with which an element loses its electrons ..

Induced currents are produced not only in the wires, but also in the block of metals. If a metallic block is placed in a continuously changing magnetic field, induced currents are set up in the body of the metallic bloc..

Induction furnace separates certain metals from their ores. It is done by heating the metal. The type of heating done is called induction heating. This heating can be done using eddy currents. The metal to be heated is placed in a high frequency changing magnetic..

Pure iron is a grey white metals. It appears to be brown due to rusting. It is malleable, ductile and magnetic. A good conductor of heat and electricity. Iron has a high density and high melting poi..
