I'm trying to create a variable inductance in SPICE, specifically in NI Multisim. What I'm trying to do is create a saturable inductor. I need an inductor that changes it's inductance with current. Multisim does have a "virtual" inductor that you can create a inductance function with but I can't really get it to work and I used NI but their help isn't that great either. Has any created a variable inductor or a saturable inductor in some sort of a SPICE program (or Multisim)? Any help is greatly appreicated. Thanks!
