The laminations are indeed hard, but they still yield to a grinding wheel..

However, it is not the laminations which you need to grind through, it is
the weldment (likely MIG) which connects the "E" part to the "I" part. *Here
are pictures of a little one that has been opened up:

In the first picture you can see the seperate "E" and "I" laminations. *The
red arrows show the location of the welds which were placed at the factory
to hold the "E" to the "I". *In the second picture, you can see where the
welds were removed using an angle grinder.

Ok, I understand. I've cut some transformers like that, but I thought
that he was cutting an MOT in half to make two electromagnets. I
guess it not really necessary to cut it exactly in half, but I'll
probably have to find a few MOTs to experiment with. Thanks.
