Dr. Meeker said the wLi contributes to the circuit's resistance. Does it 
mean that when I calculate the complex inductance, the multipilication of 
imaginary part of inductance and angular freqeuncy should be same resistive 
loss?  At least the simualtions I played with, I could not get any 
correlation. The imaginary part of inductance is too low.

No, the loss that you get by calculating (1/2)*omega*Li*i^2  is just the core loss.  This is in addition to the resistive losses in the coils.

Dave.
