I have measured the primary inductance of a low frequency transformer at different frequencies, with 10Khz it is 2.2mH and at 100Khz it is 460uH. It has a resonant of about 800khz
With the following equations
L=n^2*AL
L=(3.2*n^2*u*A)/(10^8*l)
I guess I am right in saying the AL has a direct relationship with the permeability of the core material for the top equation to be correct, the frequencies must be to low for any capacitance to have any effect on the inductance. If I am right in saying so, what is the relationship with AL to the permeability is it?????
AL=(3.2*u*A)/(10^8*l)????
