I was under the impression that file(1) uses libmagic which inturn reads a
file of 'magic' patterns for the tests and the same file also has the 'file
type string' to be printed.

And looking at libmagic(3)

  ...
  The magic_file() function returns a textual description of the contents of
  the filename argument, or NULL if an error occurred.  If the filename is
  NULL, then stdin is used.
