Funny, I watched the embedded video yesterday. It gives a very good explanation of how the core worked, including a lot of theory and implimentation details. They wire up an actual core, and write a bit, then read it back by detecting core flips with an oscilloscope. It's a bit long, but well worth the time to watch.
