The magnitude of the magnetic field around the conductive line, of which the current flow is I (A), is inversely proportional to the distance R (m) from the conductive line and, it can be obtained as follows.

B = k*I/R

B : magnitude of magnetic field (N/A¡¤m = T = Wb/m^2)
k : proportional coefficient = 2*10^(-7) N/A^2
I : current flowing in the conductive line (A)
R : distance from the conductive line (m)

Expressing the result in the unit of ¥ìT,

B = 2*10^(-7)*I/R*(10^6)

= 0.2*I/R
