Why this rock is probably not a meteorite:

This rock does not have a fusion crust and the exterior is not smooth like a meteorite.

The rock was found in a corn field in Pennsylvania. It is strongly attracted to a magnet. It has holes, however. Stony meteorites that contain metal (chondrites) don't have holes or vesicles.
What is it?

Perhaps it's a piece of slag. Slags typically have vesicles because they were at least partially molten and there was gas in the melt. Chondrites do not form from a melt, which is why they don't have vesicles.
