Difference between diamagnetic paramagnetic and ferromagnetic materials pdf
Ferromagnetic materials become magnetized when the magnetic domains within the material are aligned. This can be done by placing the material in a strong external magnetic field or by passing electrical current through the material.
may also be paramagnetic or ferromagnetic, and their positive paramagnetic or ferromagnetic susceptibilities may be larger than their negative diamagnetic susceptibility, so that their overall susceptibility is positive. But all materials are diamagnetic, even if their diamagnetism is hidden by their greater para- or ferromagnetism. A proper account of the mechanism at the atomic level of the
We will begin by looking at diamagnetism in materials with no permanent magnetic moments, then paramagnetism in materials with mag- netic moments that do not interact with each other. Finally, we consider materials where there is strong interaction between the magnetic moments, leading to ferrormagnetic, anti-ferromagnetic, or ferrimagnetic behaviour. 2.1 Diamagnetism Diamagnetism …
Ferromagnetic materials will respond mechanically to an impressed magnetic field, changing length slightly in the direction of the applied field. This property, called magnetostriction, leads to the familiar hum of transformers as they respond mechanically to 60 Hz AC voltages.

The material response on the applied magnetic field can be used to distinguish the basic classes of materials: diamagnetic materials, paramagnetic materials, and ferromagnetic materials. In all the cases the principal origin of the magnetic properties lies in electron cloud of the atom of a given species. The following phenomena can be observed:

FERROMAGNETIC MATERIALS 7.1 What are ferromagnets? Earlier, in Section 6.2, we considered the following visualization of atomic dipoles in a material in a uniform applied B field: B x10 9 aligned atomic dipoles In diamagnetic and paramagnetic materials the alignment is small. In ferromagnetics, alignment is almost complete over regions called domains magnetization direction within a particular
Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances the weak diamagnetic force is overcome by the attractive force of magnetic dipoles in the material.
On the contrary, diamagnetism mostly comes from the complete shells. They behave as electric current loops that orient themselves in a certain way in the external magnetic field. They behave as electric current loops that orient themselves in a certain way in the external magnetic field.

Ferromagnetic solids have atoms with magnetic moments, but unlike the paramagnetic case, adjacent atomic moments interact strongly. The effect of interaction is to produce magnetizations in ferromagnetic solids
This difference between diamagnetic and paramagnetic substances is caused by the absence or presence of the magnetic moments that some materials possess in atoms, ions, or molecules.
Distinguish between ferromagnetic, paramagnetic and diamagnetic materials Ferromagnetic Materials:- These are materials in which magnetic dipoles interact in such a manner that they tend to line up in parallel.
The difference between spontaneous magnetization and the saturation magnetization has to do something with magnetic domains. Saturation magnetization is an intrinsic property, that is independent of particle size but is dependent on temperature. Paramagnetic susceptibility is slightly greater than 1 and is positive but, ferromagnetic susceptibility is high and positive. When compared with

Magnetic susceptibility of a material is the property used for the classification of materials into Diamagnetic, Paramagnetic and Ferromagnetic substances. The material is Diamagnetic if the value of χ is small and negative, Paramagnetic if the value of χ is small and positive and Ferromagnetic if the value is large and positive.
