Inductor in an Amplifier Circuit

This model shows how to combine an electric circuit simulation with a finite element simulation. The finite element model is an inductor with a nonlinear magnetic core and 1000 turns, where the number of turns is modeled using a distributed current technique.

The circuit is imported into COMSOL Multiphysics as a SPICE netlist, which merges the inductor model and the circuit elements as ODEs.

The global plot shows the input signal (sim_VIN_v), output signal (sim_RL_v), and inductor voltage (sim_X1_v) as functions of time.
