Multi-Layer Coil Inductance Theory Vs Simulation

Please login with a confirmed email address before reporting spam

Hi All,

I m trying to compare the inductance value for a circular multi-layer coil inductor between:

The theory given by many online calculator (based on maxwell algorithms for most of them) : electronbunker.ca/eb/InductanceCalcML.html coil32.net/online-calculators/multilayer-coil-calculator.html www.pronine.ca/multind.htm or www.tesla-institute.com/!app/sim/acic.php all this website give really close results.

And a comsol 2D axissymetric simulation with the same parameters (coil length, number of turns, inner and outer diameter, wire gauge) using "multi-layer coil" of the AC/DC module.

I found quite big differences between theory and simulation for the inductance value (more than 40% for some exemples).

Does someone have a explanation for that difference ?

Note: the equivalent resistance value of the inductor between theory and simulation are really close.

Thanks
