IPython %store magic not persisting

I'm trying to get an IPython alias to persist, and according to docs the %store magic offers this feature. But it's not working:

$ echo 'print("hello world!")' > test.py
$ ipython
In [1]: alias potato python /tmp/test.py

In [2]: potato
hello world!

In [3]: %store potato
Alias stored: potato (python /tmp/test.py)

In [4]: 
Do you really want to exit ([y]/n)? 
$ ipython
In [1]: potato
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-1-e561f9248d75> in <module>()
----> 1 potato

NameError: name 'potato' is not defined

What's missing?

@ecatmur's solution worked for me. Thanks! I want only add an example how to add a startup script. Just add .ipy file to .ipython/profile_default/startup/ directory with following content %store -r:

[ikors@localhost ~]$ cat .ipython/profile_default/startup/startup_script.ipy
%store -r

You can also restore in a regular script, for instance if your IDE (Spyder) doesn't support the ipython_config.py file:

from IPython import get_ipython
ipython = get_ipython()
ipython.magic("store -r")

(Put this in a file that's called in the Startup tab of Spyder's IPython configuration. This took me way too long to figure out.)

You need to run %store -r to retrieve stored variables (and aliases).

Of course, you can add this to your ipython startup script.
