"Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. Such memory is often just called core memory, or, informally, core.

Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite) as transformer cores, where each wire threaded through the core serves as a transformer winding. Three or four wires pass through each core.

Each core stores one bit of information. A core can be magnetized in either the clockwise or counter-clockwise direction. The value of the bit stored in a core is zero or one according to the direction of that core's magnetization."

I understand this.The basic concept, Quite well actually. You store a 1 or a 0 on a transformer, or in the case of tape, you magnetise or demagnetise a line.

That is not a problem for me.

But what I am looking into right now is how the registers worked.

It seems the registers were well, registers that held the location of all sets of instructions.

So if you wanted to process code, you would have to refer to the register to know what is where. And align the head accordingly.

But this also means that registers need to have a mechanism to talk to loops and modify themselves according to the loop count.

so it seems like registers also needed some form of memory to be able to do that.

I dont know if this sounds like gibberish
