In my experience senior professors have argued this very concept passionately
for decades - and so it continues!!

there is not any loop for the partial self inductance it's just the inductance
of the wire itself

Thanks for all very informative replies. I have one more question:
When using infinite as the ref for calculating partial inductance, how
to determine the loop area? Does it plausibly seem to be infinite,
too? Sure this is not correct since it results in infinite inductance.
But I cannot figure out how..
Best Regards,
Tramp

Hello Tramp,referencing
the term "referencing to infinite" is used by physicists in context
of a electric field potential if the local potential changes rapidly
with location but in the "infinite". All points in a field potential
are created equal so you can choose your reference arbitrarily. The
"infinity" reference simplifies the math you are doing by forcing an
integration constant to zero.
Beware: there are some precautions to ensure before you are allowed
to use the concept of the field potential. In the SI domain there is
no field potential besides some carefully configured situations.
Generally, there is no "ground" in SI.

Hi experts,
Sometimes I came across the term "referencing to infinite" in SI
literatures. I wonder what differences would there be between
to infinite and referencing to local ground? Actually I have noabout
idea
how to set up a port in 3D sim tools which references to infinite...
Best Regards,
Tramp
