Hello !!! I have a question how to calculate the inductance of the Henr's coil ?? Are there any formulas to calculate this value ?? Eg wire thickness, coil diameter, number of turns ?? Can you calculate the inductance from this ?? What are the patterns for this ?? GREETINGS :) Kamil

Probably it is possible, of course only to determine the estimated inductance. This seems to be the pattern in Roman Kurdziela's book Elektrotechnika for basic schools (part 1). - unfortunately I do not have it at the moment and I am not able to help.

Hello Look at this: (heh there is nothing like google 2 minutes of searching) Regards

If you want to calculate inductance, we use the formula: H = (Z * J) / l where: H - inductance you want to have Z - number of turns J - the current flowing through the wire in the coil l - coil cross section when it comes to the wire cross-section, you have to give one so that it does not burn :D The formula is for the air coil because you haven't written for what you want

Oh, the cross section of the coil is it about the thickness of the wire or what? And for the core, what will the pattern be ?? Because it depends on the core too !!

As for the air coil, I saw a nomogram somewhere from which it would be possible to approximately determine the inductance. In the case of the core, this calculation is practically impossible due to the high non-linearity of the core. Only a meter with inductance measurement. Good luck...

If you want to calculate inductance, we use the formula:

H = (Z * J) / l

where:
H - inductance you want to have
Z - number of turns
J - the current flowing through the wire in the coil
l - coil cross section

when it comes to the wire cross-section, you have to give one so that it does not burn :D

The formula is for the air coil because you haven't written for what you want
