What kind of glass-safe magnet should I get in order to retrieve a magnetic stirrer from an erlenmeyer flask? I don't want to go overboard. Thanks.

You need a magnetic stir bar retriever, like this

You can simply use another magnetic stir bar or any other magnet. hold it outside the flask next to the stir bar inside the flask, carefully slide the outer magnet to the side and then towards the neck, pulling the stir bar inside the flask with it, and finally, use your fingers!

Oh this is exactly what I was looking for. I'll test to see if the stirrer itself is strong enough before I purchase this.
