The Magneto has a pretty exclusive system with the magnets, as in you won't have much luck switching them to a different
mod.
Here's a video for the Chi You:

Some mods aren't really made for magnets, though. I has a Pisces-T and an Atom, and the throws were so short I couldn't really imagine how to make them work with magnets. Others, like my Galileo, has the locking ring connected to the button, which made it hard to lock the
mod with magnets instead of the spring (it would just spin freely).
Hope this helps somewhat!
