Look carefully. There are thousands of little round ferrite donuts. Each one held a magnetic polarity, set by the wires going through them. If the polarity was in one direction, the value was zero. If the polarity was in the other direction, the value was one. Each donut was one bit. There are four wires through each magnet.
