The cause of magnetization for these substances is the orbital motion of electron in which velocity of the electron is affected by the external magnetic field. Science > Physics > Magnetism > Types of Magnetic Materials In this article, we shall study types of magnetism, types of magnetic material, and Curie temperature. Paramagnetic materials include oxygen and ions of various metals like Fe (iron), Mg (magnesium), and Gd ().These ions have unpaired electrons, resulting in a positive magnetic susceptibility. Diamagnetism is a weak magnetism and is the fundamental property of all matter.. Diamagnetism is mainly due to the non-cooperative behavior of the orbital electrons under the application of an external magnetic field.. 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 (i) Properties of diamagnetic substances . 30 Minutes Properties of different classes of magnetic materials: Now we are going to study the various properties of magnetic materials in terms of the magnetic properties of the atomic dipoles and the interaction between them. Diamagnetic, Paramagnetic, and Ferromagnetic Materials When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. Diamagnetic substances are those which have a tendency to move from stronger part to the weaker part of the external magnetic field. Paramagnetic: They are weakly attracted by the magnetic fields.

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. On the basis of magnetic behaviour magnetic materials are classified into three types: diamagnetic, paramagnetic, and ferromagnetic substances. The key difference between diamagnetic, paramagnetic and ferromagnetic materials is that diamagnetic materials are not attracted to an external magnetic field, and paramagnetic materials are attracted to an external magnetic field whereas ferromagnetic materials are strongly attracted to an external magnetic field. Therefore, the magnetic field cancels out and the material appears to behave in the same way as a paramagnetic material. Diamagnetic materials are materials that give rise to a magnetization opposite to any magnetic bias field that might be applied to the material. Paramagnetic materials such as aluminum and air have permeability’s slightly greater than that of free space (for air μ r =1.0000004). The concept of Ferromagnetism, Paramagnetism and Diamagnetism is completely different, though they all show magnetic properties. What do we understand by a paramagnetic material? We see that the field lined get repelled by the material and the field inside the material is reduced. Answer: Copper isn't ferromagnetic, Aluminum isn't ferromagnetic, String has a ferromagnetic property Explanation: first of all it is important to understand that all materials have diamagnetic effect. O 2, Cu 2+ etc. Now customize the name of a clipboard to store your clips. Properties of Diamagnetic,Paramagnetic, Ferromagnetic substances NaCl, Benzene: Behaves like an insulator. All magnetic materials may be grouped into three magnetic classes, depending on the magnetic ordering and the sign, magnitude and temperature dependence of the magnetic susceptibility. Based on the magnetic properties, materials can be divided into five main categories; diamagnetic, paramagnetic, ferromagnetic, ferrimagnetic and antiferromagnetic. See our Privacy Policy and User Agreement for details. Ferromagnetic materials or substances are invented by a French physicist Louis Eugene Felix Neel. The size of μ permanent atomic dipoles create spontaneously magnetized. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom.It can thus be said that each electron of an atom behaves like a magnet, lending the whole solid its magnetic property. For example: aluminium, tin magnesium etc. The materials which are repelled by a magnet such as zinc. 5. 3. Diamagnetic materials - definition Diamagnetic materials create an induced magnetic field in a direction opposite to an externally applied magnetic field, and are repelled by the applied magnetic field. In diamagnetic substances, all the atoms have paired electrons and there are no unpaired electrons in … Matter A few materials, notably iron, show a very large attraction toward the pole of a permanent bar magnet; materials of this kind are called ferromagnetic. 1.
