Permeability of paramagnetic materials

Relative magnetic permeability of diamagnetic materials is always greater than unity that is

μr > 1

Conceptual explanation:

Do you know that permeability word comes from the word “permission”? As it is the natural property of diamagnetic material to weakly attract the lines of force (due to structure of paramagnetic material). Now, if they weakly attract the lines of force or in other words they permit the magnetic lines of force to pass through it but weakly. Therefore, the μ > 1 for paramagnetic materials

Analytical Explanation:

When a specimen of paramagnetic material is placed in a magnetising field, the Continue reading “Permeability of paramagnetic materials”

Susceptibility of paramagnetic materials

Logical Answer:

Susceptibility comes from the word “susceptible” means the easily affected. As I have discussed earlier that lines of force are weakly attracted towards paramagnetic materials, when these materials are placed in external magnetic field. It means paramagnetic materials are weakly effected by the field. Therefore the susceptibility of diamagnetic materials is positive but small.

Analytical Reason:

As we have discussed in the earlier articles, that relative permeability of Continue reading “Susceptibility of paramagnetic materials”

Properties of paramagnetic materials

Paramagnetic materials have following properties:

  • In paramagnetic materials, the magnetic lines of forces due to the applied field are attracted towards the paramagnetic material.
  • When suspended in a uniform magnetic field, paramagnetic materials rotate so as to bring their longest axis along the direction of the magnetic field and shorter axis perpendicular to the field. Continue reading “Properties of paramagnetic materials”
