The EMACSLOADPATH environment variable is set when installing Emacs
itself; have you installed the 'emacs' package in your profile (guix
install emacs), then sourced your profile again
(. ~/.guix-profile/etc/profile), or alternatively started a new shell?

This works for me, for example:

--8<---------------cut here---------------start------------->8---
$ guix shell --container emacs emacs-magit -- emacs --batch --eval \
  '(begin (print (getenv "EMACSLOADPATH") (print (magit-version))'
Loading /gnu/store/hsj3kl0vc3hxiapklg5nj42z5jb4s80p-emacs-magit-3.3.0/share/emacs/site-lisp/magit-3.3.0/magit-autoloads...
[...]
"/gnu/store/zv9iqvv6jnnvf0cr0c8kan3dcgj8mybj-profile/share/emacs/site-lisp:/gnu/store/ybpddmq7f8ajzydhiqqx6dldgmadqanp-emacs-27.2/share/emacs/27.2/lisp"

"3.3.0"
--8<---------------cut here---------------end--------------->8---

HTH,

Maxim
