History Of Magnetism
Everything around us is made up of electrons and they are continuously moving. So one might ask why everything around us is not a magnet including ourselves. The answer to this is, that individual electrons moving around any object behave as a magnet but overall all these small magnets cancel out each other’s magnetic property and thus not all material behaves as a magnet.
In some materials, all the electrons are arranged in such a way that they do not cancel each other and they are called ferromagnetic material. These ferromagnetic materials are called permanent magnets as they attract other metallic materials naturally. The property of magnetism is first observed in a material called Magnetite(Fe3O4) hence the name magnets. These magnetite is scattered all around the Earth’s crust and was first noticed by a shepherd in Greece.
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.
