What is the magnetic moment of a rectangular loop of 120 turns that carries 6.0 A if its dimensions are 4.0 cm × 8.0 cm?

Question

Quizplus · Accepted Answer

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