Question

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

Answer:

40000 Am²

Explanation:

N = 500 turns

I = 2A

A = 4 m x 10 m = 40 m²

Magnetic moment M = N × I × A

= 500 × 2 × 40

= 40 × 10³ Am²

= 40000 Am²
