Nope. High flux close to the knee => close to saturation. A minute amount of
DC is enough to saturate the core.

So don't put DC in it then ! It's a non-problem for power transformers.

Yeah, sure. And what about mains DC offset?

WHAT mains DC offsets ?

I suppose such things might exist in 3rd world countries.
