properties of solid materials

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects tha..

Magnetic Properties of Solids - The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axis. A m..

The magnetic properties of materials are a consequences of magnetic moments associated will individual electrons. The magnetic moment of an electron is due to its orbital motion and also due to its spin around its own axis. A moving electron may be considered to be a small curre..

Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic momen..

Materials such as glass containers, plastic bags, paper, cloth etc. can be reused at domestic levels rather than being disposed, reducing solid waste pollutio..

(e.g., O 2 , Cu 2 + , Fe 3 + ) are attracted by a magnetic field but lose their magnetism in the absence of the magnetic field. This property is shown by those substances whose atoms, ions or molecules contain unpaired electron..

Properties of solids have been exploited for various new innovations in electronic and magnetic devices like transistors, computers, telephones etc. Properties of the solids mainly depend upon their structure and composition. Three main properties a..

On the basis of their magnetic properties different materials are classified as: Diamagnetic substance Paramagnetic substance Ferromagnetic substan..

Dielectric Properties of Solids - Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attract..

Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attracted towards cathode and electron cloud towards an..
