Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
That was the dumbest way to make it flat.
I never try this on a microwave transformer winding, but if you open regular one and connect to a AC it will boil and die. Ya know, you drastically increase air gap, thus inductance fall, so AC mains see only wire with very little inductance.
So my question is, how is he dealing with temperature, so as long, as he would "short" that magnetic core with some element, everything should be ok, but when transformer is "open", coils will generate heat. Is microwave transformer winding so high in numbers, that heat isn't that big of a deal?
Or he is powering it from lower voltage? I understand how electromagnet works, but still its not the same thing as transformer with one side cut off.
