Come to think of it, that would be a nice thing to have as a command,
wouldn't it?  But hack-local-variables is the function that gets
called when you find-file a file, so you can just put this in your
.emacs:

  (defun my-reparse-local-variables ()
     (interactive)
     (hack-local-variables))

  (global-set-key ... #'my-reparse-local-varaibles)
