Inductance is an intrinsic property of current carrying conductors and is often explained by induction. But this does not work for DC. It is much more straightforward to understand the inductance in terms of the magnetic field.

Ferrite clamps are used to filter common mode currents and they are often explained by losses. But that does not work at low frequencies. It is much more straightforward to understand them as inductances.

In this presentation, we will see how 3D simulation can help you to better understand these basic concepts.
