Calculating impedance of a single-turn coil suspended in a poly-amide

Please login with a confirmed email address before reporting spam

The below post is related to an [archived discussion](/forum/thread/27276/calculating-impedanc Hello all,

I am trying to calculate the impedace of a coil suspended in a polyamide using EC and MF physics in time-domain study. After giving an input sinusoidal wave V(t), I calculate the current, I(t) by using a surface integration and then export the value of V(t)/I(t) to calculate the Z.

Is this the right approach to do? Theretically, Z should be equal to XL; but upon calculating the XL= 2pifL ( L=2W/(II)), W being the total magnetic energy, the XL value doesn't match with the Z value calculated using V(t)/I(t).

I wanted to use global evaluation to calculate th impedance, but I don't know how it works. I would be really grateful if someone kindly help me out about this. I have attached the .mph file for convenience.
