(a) A closely wound solenoid of 2000 turns and area of cross-section , carrying a current of 4.0 A, is suspended through its centre allowing it to turn in a horizontal plane. What is the magnetic moment associated with the solenoid?
Answers (1)
Given,
Number of turns, N = 2000
Area of the cross-section of the solenoid, x
Current in the solenoid, I = 4 A
We know, The magnetic moment along the axis of the solenoid is:
m = NIA
= (2000)(4 A)(1.6 x )
= 1.28
