Inductor wire

Here is my approximation.
I used Sweep for the coil and Revolve for the core. I rotated the top coil sketch 10° to the right and the bottom coil sketch 10° to the left and did a sweep. I copy rotated the coil 19.4° about the XYZ axis. The 19.4° is an approximation as I just eyeballed it. Anyway, this is one approach to create the inductor wire.
