I just meant that students might expect "Out" poles to display
positive magnetic flux and "In" poles to display negative magnetic
flux.
Is that so bad? +/- are correctly? often used to indicate directions.
Is the problem they will ascribe to + or - more than just a direction?
I'm still trying to see the confusion with G's law. An Out 'pole'
within the gaussean surface WOULD make a mathematically positive
contribution to the total flux. Some or all of the Out poles
contribution could be counterascted by any In poles that also are
within the surface in question.
If your objection is that G's Law can be confused by the concept of
Poles, then I agree. I am suggesting that IF poles remain in the
students science vocabulary, then it would be better for them to be
considered as being Out and In poles (or Ludwik's choice of Head an
Tail also has that nice warm intuitive feel that we all seek so
diligently ;-)
