Explanation / Answer

Here,

u = 1.256 *10^-6 T

total current, I = 7 mA

let us take a circular amphere loop with radius = 3.6 cm

Now , Using Amphere circuital law

B * 2pi * r = u * Iin

B * 2pi * 0.036 = 1.256 *10^-6 * 0.007 * pi * (0.036^2 - 0.03^2)/(0.07^2 - 0.03^2)

solving for B

B = 1.21 *10^-8 T

the magnetic field at this point is 1.21 *10^-8 T
