Q.5. What do you mean by paramagnetic materials? Describe its different properties.

Dear Student

Materials when placed in a magnetic field, possesses magnetization in direct proportion to the field strength. These are materials in which the magnetic moments of the atoms are not aligned.

• 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.
• When placed in a non-uniform magnetic field, the paramagnetic materials move from weaker parts of the field to the stronger parts.
• Permeability of paramagnetic material is greater than 1
• Magnetic susceptibility of paramagnetic material is positive but small.
