### Inductance - Wikipedi

Since the total flux linking the coil is then: and the total self-inductance is just that flux times the total number of turns: so that the self-inductance is: Since, in our case, there are 66 turns, the inductance works out to be: L = 1.39 mH. We would expect the inductance derived from finite element computations to be in the neighborhood of. Contrary, if the coil would be compressed to make it flat, the inductance value of the coil will be increased. In case of litz wire, if the frequency increases, the inductance value goes up. To enhance Q- factor & Inductance value in case of litz wire, each wire can be stuck together very tightly by self-bonding fabricating and controlling pitch calculation
