## Main Question or Discussion Point

Hi,

I am trying to figure out how to calculate the permeability constant of a lot of plastics by making solenoid (because that seemed to be the best method of doing so). I am currently using: μ=Ll/((N^2)A) to calculate that constant. Using this method I will only need an induction meter which can easily be a part of an LCR meter but is this the method you would advise me use?
