What is the magnetic moment of a rectangular loop having 120 turns that carries 6.0 A if its dimensions are 4.0 cm × 8.0 cm? A)0.23 A ∙ m² B)2.3 A ∙ m² C)23 A ∙ m² D)230 A ∙ m²

Question

The magnetic moment (μ) is given by μ = N * I * A, where N is the number of turns, I is the current, and A is the area of the loop. The area A = 0.04 m * 0.08 m = 0.0032 m². Thus, μ = 120 * 6.0 A * 0.0032 m² = 2.3 A ∙ m².
