Order is Important
I have been stuck with related problems several times, the example below shows when assume will and won't be effective:
Simplify[Assuming[p \[Element] Reals, Conjugate[p]]]
returns:
Conjugate[p]
Assuming[p \[Element] Reals, Simplify[Conjugate[p]]]
returns:
p...
So... back to my original question:
Does this imply that the inductance of a solenoid, frequently quoted in textbooks, is actually wrong? as in panel 3 in my original post
So.. If we imagine that lgap is very small, then the equation should become equal to the original toroid equation. Agap will approximately equal to Airon. So... the second term in that equation appears to blow up rather than diminish to zero as should be expected.
and yes... I had an equation...
Im working with building a reluctance motor and I've posed a problem to myself that i cannot answer without questioning some long accepted facts about the inductance of a solenoid.
The simple solenoid and toroidal solenoid are two shapes that seem to have simple equations for calculating the...
