| [1], eq. (4.4), p. 107 | $$ H(t,x) = I(t) · \frac{1}{2}· \frac{r^2}{(x^2 + r^2)^{3/2}} $$ | (A/m) |
| where: $I(t)$ - current (A) at time $t$ (s), $r$ - radius of the loop (m), $x$ - location (m) from the centre of the loop (the centre is located at point x = 0); assuming infinitely thin wire and a circular loop placed in a uniform medium | ||
