NEET Physics Magnetic Properties of Materials MCQ Question
Type: MCQ-fact-Medium-Class 12
What is the relationship between magnetic susceptibility (χ) and relative magnetic permeability (μ_r) for a linear material?
A
μ_r = 1 + χ
B
χ = μ_r + 1
C
χ = μ_r - 1
D
μ_r = χ + 1
Correct Answer
Option A
Detailed Explanation
For a linear material, the relationship is given by μ_r = 1 + χ, indicating how susceptibility relates to permeability. This is stated in the NCERT context where χ and μ_r are discussed.
