Question

11 A closely wound solenoid of 500 turns and area
of cross section 4 x 10 m carries a current of
2A. Calculate the magnetic moment of solenoid.​

Answer 1

Explanation:

Given :-

Current I = 2 A

No. of turn N = 500

Area of Cross section A = 4 × 10 m

Magnetic Moment M = ?

• M = N × I × A
• M = 500 × 2 × 40
• M = 4 × 10⁴

Answer 2

Answer:

Given

current | = 2A

no. of turn N =500

Area of cross selection A = 4 × 10m
