FISH = 0.5*2mH*(1A^2 - 0A^2) = 1mJ

now let Imin = 100A, Ipeak = 101A, then according to you,

FISH = 0.5*2mH*(101A^2 - 100A^2) = 201mJ


ROTFLMAO!

next you will be asserting that the change in energy stored in a cap is 0.5*C*(Vfinish - Vstart)^2 :)

whereas I can confidently state this is not the case; try throwing constant quanta of energy into a cap, and watch the incremental voltage get smaller each time.....




<snipped more mixed garbage and good stuff>

LOL.



which ends up as

Pin = (V*D)^2/(2*Lp*Fsmps)


so so?
So do those formulae answer the Op's query. How so? Any average
intelligence engineer could write an entire book on a flyback
transformers(without basic errors) but the current problem is
answering the man's question.


best not to review that sentence given your glaring fundamental error!

enjoyable play, till later if i have time.

Ha! that explains.
Ask lemonjuice what he thinks about amplifiers noise :-)

Worth its weight in peanuts...
