Magnetic Materials
All the materials around us can be categorized into three types that are,
- Diamagnetic Materials
- Paramagnetic Material
- Ferromagnetic Materials
Diamagnetic Material: In general most of the materials around us have diamagnetism. In this material, they have paid electrons and thus they have no magnetic property. Examples of Diamagnetic Materials are Copper, Gold, Silver, etc.
Paramagnetic Materials: The materials that have unpaired electrons are called paramagnetic materials and they show paramagnetism, i.e. they experience some force inside the magnetic field of other magnets. The magnetic moment of the electrons does not align in the case of the paramagnetic materials. Examples of Paramagnetic materials are Magnesium, Lithium, etc.
Ferromagnetic Materials: There are very few materials that have ferromagnetism and they can be made permanent magnets. In ferromagnetic materials they have unpaired electrons and their magnetic moment is free to align itself freely. Examples of Ferromagnetic materials are, Iron, Cobalt, and Nickel.
Magnetism
Magnetism in Physics is defined as the property of the material that is responsible for the magnetic behaviour of the magnets. Magnetism is defined as the force that is produced by the moving charge and it attracts or repels other magnets and moving charge. Initially, magnetism is defined as the property of some material to attract or repel some other magnets. Later it was discovered that all the moving charges are considered to be magnets and their property of attraction or repulsion is called magnetism.
Here, in this article, we will learn about, Magnetism Definition, History of Magnets, Causes of Magnetism, Magnetic Materials, Properties of Magnets and others in detail.
