Reply To: Q3D simulation magnetic device with ferrite core

[Travis Huang]

We guess that the current in ferrite core is not conduction current, but displacement current. Displacement current reflects the time-varying electric field in the core, which has nothing to do with the conductivity. We try to see the difference in the current in the core by changing the permittivity of core material. Unfortunately, we still can not observe the difference even though we have increased the relative permittivity to 1000.
