Practice question

Given: A paramagnetic material with chi = 2 × 10⁻³ is placed in H = 500 A m^{-1 . What is 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 = 2 × 10⁻³, H = 500 A m^{-1 . M = 2 × 10⁻³ × 500 = 1 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.
