Certain materials posses permanent magnetic moments in the absence of an external magnetic field This is known as ferromagnetism Permanent magnetic moments in ferromagnetic materials arise due to uncancelled electron spins by virtue of their electron structure The coupling interactions of electron spins of adjacent atoms cause alignment of moments with one another The origin of this .
Properties of diamagnetic, paramagnetic, ferromagnetic ,
Classification of magnetic materials : On the basis of the behaviour of materials in a magnetising field, the materials are generally classified into three categories namely, (i) Diamagnetic, (ii) Paramagnetic and (iii) Ferromagnetic
Classification of Electrical Engineering Materials ,
2018-07-27· Materials used in the field of Electrical Engineering are called the Electrical Engineering materials Based on properties and area of applications, Electrical Engineering materials can be classified as below- Conductors Semiconductors Insulators Magnetic material A classification chart of electrical engineering materials is shown in figure .
74 Classification of Magnetic Materials - Engineering ,
74 Classification of magnetic materials By the application of magnetic field, some materials will not show any effect that are called non-magnetic materials and those which show some effects are called magnetic materials
Magnetic Material Classification - Engineering Physics ,
Answer: c Explanation: Magnetic materials are the materials which can behave like magnets When these materials are kept in an external magnetic field, they will create a permanent magnetic moment in it
Those substances which are feebly magnetized in the direction opposite to the applied field are called diamagnetic material Those materials which are weekly magnetized in the same direction of the applied magnetic field are called paramagnetic material

2017-08-06· The magnetic materials are classified into 5 types Diamagnetic Material Paramagnetic Material Ferromagnetic Material Anti-ferromagnetic Material Ferri Magnetic Material 1 Diamagnetic Material These material have smaller and negative magnetic susceptibility These material are repelled by applied magnetic field The magnetic flux density inside .
Magnetic Properties of Materials - Study Material for IIT ,
Magnetic Properties of Materials Magnetic Field: The magnetic field is an imaginary line of force around a magnet which enables other ferromagnetic materials to get repelled or attracted towards itThe magnetic field lines are formed due to various reasons like orbital movement of electrons, current flowing in a conductor etc
PROPERTIES OF MAGNETIC MATERIALS 121 Introduction This chapter is likely to be a short one, not least because it is a subject in which my own knowledge is, to put it charitably, a little limited A thorough understanding of why some materials are magnetic requires a full course in the physics of the solid state, a course that I could not possibly give Nevertheless, there are a few basic .
Classification of Magnetic Materials All materials can be classified in terms of their magnetic behaviour falling into one of five categories depending on their bulk magnetic susceptibility The two most common types of magnetism are diamagnetism and paramagnetism, which account for the magnetic properties of most of the periodic table of elements at room temperature (see figure 3) ,
Different Types of Magnetic Materials and its , - Blogger
A material contains a large number of electrons and the orbits of these electrons are randomly oriented in space The current that is produced due to movement of electron in an orbit produces magnetic field in a direction at right angles to the plane of the orbit
All substances show some kind of magnetic behavior After all, they are made up of charged particles: electrons and protons It is the way in which electron clouds arrange themselves in atoms and how groups of these atoms behave that determines the magnetic properties of the material
CLASSIFICATION OF MAGNETIC MATERIALS | Electrical ,
All materials possess magnetic properties to a greater or lesser degree and these are determined by the facts that (1) a magnetic field exert forces and torques on the bodies, (2) a body place in a magnetic field distorts the field
Magnetic And Non-Magnetic Materials | Classification Of ,
28 Magnetic and non-magnetic materials (ESAAJ) We have now looked at a number of ways in which matter can be grouped, such as into metals, semi-metals and non-metals; electrical conductors and insulators, and thermal conductors and insulators
