UNESCO – EOLSS SAMPLE CHAPTERS MATERIALS SCIENCE AND ENGINEERING – Vol. What makes a material magnetic, ferromagnetic materials and how they can be magnetised, temporary and permanent magnets and the mineral magnetite. Like Ferro- magnetism, anti-Ferro-magnetism is associated with domain structure and exchange coupling between adjacent spins but the alignment of spins within a domain is anti-parallel (fig. The permeability of a magnetic material is 0.9983. Individual constituents do not have net magnetic moment on their own. (Delhi 2011) Answer: It represents diamagnetic materials… Ferromagnetism in Physics. These materials are strongly attracted to magnets and exhibit Paramagnetism to a phenomenal degree. This class of materials is called paramagnetic. The susceptibility is however is also very small: 10-4 to 10-5. The ideal material for making permanent magnets should possess high retentivity (residual magnetism) and high coercivity so that the magnetisation lasts for a longer time. Ferromagnetic Material – Strong magnetism in the direction of the 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 Uses of ferromagnetic materials (i) Permanent magnets . 18.
