On the far right of the LTSpice toolbar there is an icon (the ".op" one)=20
for creating a SPICE directive. CLick on this and add Kn Ln Ln Kf, where=20
n is the number of your components and Kf is the coupling factor.
Example:
You have two inductors, L1 and L2. You want to couple them with a factor=20
of 0.9, so you click on the .op icon and write:
K1 L1 L2 0.9 (K could be any number, e.g K2, K3, etc depending on how=20
many couplings you have in your circuit)
Place the directive on the schematic somewhere and you're done.
