Calculate the magnitude of the magnetic field at a point

Calculate the magnitude of the magnetic field at a point 123 cm from a long, thin conductor carrying a current of 1.47 A. The permeability of free space is 1.25664 × 10−6 T · m/A.
Answer in units of T.

B = µo . I / 2π . d = 1.25664 . 10^–6 . 1.47 / 2π . 1.23 = 2.39 . 10^–7 T
