Magnetic field x-component

The x-component of the magnetic field at point [$x_k$, $y_k$] due to current source at [$x_1$, $y_1$].

Symbol
$H_x$
Unit
mH
Formulae
$\frac{-I_{EMF}}{\pi} \left(\frac{y_k-y_1}{\left(x_k-x_1\right)^2+\left(y_k-y_1\right)^2}+\frac{y_k+y_1+2p_{soil}}{\left(x_k-x_1\right)^2+\left(y_k+y_1+2p_{soil}\right)^2}\right)$
