Note that the majority of small transformers (single-phase, 100-240V, 50hz/60hz, laminated core) are shell-type, with an EI-shaped core. Yet, as I understand it, they have comparatively poor productivity due to the visibility of much of their surface area; not wire wounds. There is also a lot of...
I'm struggling to keep my mind wrapped around the function of the transformer and, in the process, regretting the days I snooze back in my Electromagnetics class as an EE student when I was a boy:) I'm searching for an abstract explanation, but not just an equivalent one. I want it to be rooted...

I have an electromagnet made from a Microwave oven transformer.
I am only using the coil with the thicker wire.
I've separated the transformer core into the "E" shaped bit and the "keeper" shaped bit and removed the other coil.
