permeability of a paramagnetic material is expected to decrease with increasing temperature because
- a)random thermal motion increases magnetic moment alignment
- b)electrons stop moving
- c)electrons go into forbidden gap
- d)random thermal motion reduces magnetic moment alignment
Correct answer is option 'D'. Can you explain this answer?

When a parametric material comes close to a magnetic field the atoms will align with the magnetic field which causes another magnetic field. Permeability is the total magnetic field divided by the original magnetic field. Increase in temperature makes it harder for the atoms to align which decreases the strength of the second field. This results in a lower total magnetic field (numerator) and thus lower permeability.

Explanation:
Introduction:
Paramagnetic materials are those materials that are weakly attracted to a magnetic field. They have unpaired electrons that align their magnetic moments in the direction of the applied magnetic field. Permeability is a measure of how easily a material can be magnetized by an external magnetic field.
Effect of Temperature on Paramagnetic Materials:
When the temperature of a paramagnetic material increases, the random thermal motion of the atoms or molecules also increases. This random thermal motion causes a disruption in the alignment of the magnetic moments of the unpaired electrons.
Explanation of the Correct Answer:
The correct answer is option 'D' - random thermal motion reduces magnetic moment alignment. Here's why:
1. Random Thermal Motion:
As the temperature increases, the random thermal motion of the atoms or molecules in a material also increases. This leads to a greater degree of disorder in the material.
2. Alignment of Magnetic Moments:
In a paramagnetic material, the unpaired electrons have magnetic moments that can align with an external magnetic field. However, the random thermal motion disrupts the alignment of these magnetic moments.
3. Effect on Permeability:
Permeability is a measure of how easily a material can be magnetized by an external magnetic field. When the random thermal motion disrupts the alignment of the magnetic moments, it becomes more difficult for the material to be magnetized.
4. Decrease in Permeability:
As the temperature increases and the random thermal motion becomes more pronounced, the alignment of the magnetic moments decreases. This results in a decrease in the permeability of the paramagnetic material.
5. Conclusion:
In summary, the permeability of a paramagnetic material is expected to decrease with increasing temperature because the random thermal motion disrupts the alignment of the magnetic moments of the unpaired electrons. This reduces the ease with which the material can be magnetized by an external magnetic field.
