All types of materials and substances posses some kind of magnetic properties which are listed further down in this article. But normally the word “magnetic materials” is used only for ferromagnetic materials ( description below), however, materials can be classified into following categories based on the magnetic properties shown by them: 1.
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 field.
Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel ...
Classes of Magnetic Materials. The origin of magnetism lies in the orbital and spin motions of electrons and how the electrons interact with one another. The best way to introduce the different types of magnetism is to describe how materials respond to magnetic fields. This may be surprising to some, but all matter is magnetic.
Classification of magnetic materials . Because all materials have a different atomic structure different materials react differently when placed in a magnetic field. In its simplest form, the magnetic behaviour of a material is determined by its number of unpaired electrons in each atom.
Magnetic materials are those materials that can be either attracted or repelled when placed in an external magnetic field and can be magnetized themselves. Examples: iron or its alloys which are used in various electrical appliances like generators, televisions, cassette recorders, magnetic core computer memories etc. to increase the magnetic ...
Not just any material can be magnetic. In fact, of all the known elements, only a handful possess magnetic capability and they vary by degree. The strongest magnets are electromagnets, which gain their attractive force only when current passes through them. Current is the movement of electrons, and electrons are what ...
Magnetic materials. Materials exhibiting ferromagnetism. The magnetic properties of all materials make them respond in some way to a magnetic field, but most materials are diamagnetic or paramagnetic and show almost no response.
The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change. As with magnetizing a magnet, demagnetizing a magnet is also possible.
