Calculate the magnetic moment of a closely wound coil of 200 turns having a radius 15 cm and carrying a current of 4 A.
Question
Solution 1
The magnetic moment (μ) of a coil can be calculated using the formula:
μ = NIA
where: N = number of turns in the coil I = current flowing through the coil A = area of the coil
Given: N = 200 turns I = 4 A Radius of the coil, r = 15 cm = 0.15 m (since 1m = 100cm)
The area (A) of the coil can be c Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
