I think you may get a more appropriate definition of a Magic Number by taking a peek at RFC 1661. Specifically, you may want to take a look at paragraph 6.4:
"6.4 Magic-Number Description This Configuration Option provides a method to detect looped- back links and other Data Link Layer anomalies. This Configuration Option MAY be required by some other Configuration Options such as the Quality-Protocol Configuration Option. By default, the Magic-Number is not negotiated, and zero is inserted where a Magic-Number might otherwise be used."
