I have a Fluke PM 6306 RLC meter and I was wondewring how can I measure inductance of a magnetic sheet? Do I need an extra fixture to place my sample around it? I have calculated permitivity by placing my sample between 2 metal plates and measuring capacitance. I need to measure inductance in order to calculate permeability.
Any material can exhibit inductance only if you make an inductor from it. Like you measured material permittivity, you must use a coil and measure its inductance in air, then when you put your material close to it.
-the low inductance in air,
- the lowest inductance close to a conducting plane or object (eddy currents)
- a higher inductance if close to a magnetically "effective" object like your magnetic strip
-the highest inductance if you put a magnetic core in the coil.
Depending on test frequency, certain effects are more expressed at higher or lower frequencies.
