Transformer core (eddy + hysteresis) losses

[osh1397]

The question is:

The solution is:



However, from the NCEES handbook P#58


For Eddy current losses I think they will not change.
For the Hysteresis losses the flux is raised to a power greater than 1, so, I think it would actually reduce.


right?

I believe the author of Cram for Exam said that there was a mistake on this question. I remember this was discussed in another topic on this board. I'll see if I can find that topic thread for you.

EDIT - Found the thread. Please see this link:
