Practice question

Given: A paramagnetic material with chi = 5 × 10⁻⁴ in H = 4000 A m^{-1 has magnetization M : These values define the system as per NCERT data. Formula: M = chi H. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: Given: chi = 5 × 10⁻⁴, H = 4000 A m^{-1 . M = 5 × 10⁻⁴ × 4000 = 2.0 A m^{-1 . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
