al units core

Hello,
I'm having troubles with units specified with core Al factor. For example, let's take a core with "Al=2500nH". Does that mean that one turn would produce 2.5uH, two turns 10uH etc. ?

In one book it was written that Al is specified as inductance in mH for 1000 turns. But surely this isn't the case here.

Best regards

Click to expand...
it is equivalent to Al = 2500nH/(#turns^2)..
1 turn -> 2.5uH * 1 = 2.5uH
2 turns -> 2.5uH * 4 = 10uH
3 turn -> 2.5uH * 9 = 22.5uH
and so on..
