Practice question

Given: A bar magnet with original m = 2.8 A m² is cut transversely into two equal parts. What is m of each part? These values define the system as per NCERT data. Formula: Given: m = 2.8 A m². This is standard NCERT relation. Substitution & Calculation: When cut transversely, each part has half the original magnetic moment. . Each part: m' = 2.8/2 = 1.4 A m² . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
