Explanation / Answer

According to the question we need to find the value of the inductance of the solenoid.

n = 157 turns d = 6.15 mm l= 2.11 cm

We use the formula mentioned below : L=u0*N^2*A/(l)

L = 4 * 3.14 * 10 ^ -7 * (157)^2 * 3.14 * ( 0.00307511 m ) ^2 / 0.0211 m

L = 43.56386 uH ============================ANSWER)
