hi, ı want to make 5*20 cm rectangular search coil. fistly ı search on google but almostly all coil is circular and calculations make according to circuilar. ı do not know how to make calculate inductance of rectangular search coil. how can ı calculate ınductance for example for circuilar we make these calculation::
L=((N^2)*(R^2))/((9*R)+(10*H))
where:
L = inductance in micro-Henries,
N= number of turns of wire,
R= radius of coil in inches,
H= height of coil in inches. [1]
L=((N^2)*(R^2))/((9*R)+(10*H))
where:
L = inductance in micro-Henries,
N= number of turns of wire,
R= radius of coil in inches,
H= height of coil in inches. [1]
