Can I boil my stir bars?

The magnets are in my stirplate, so I can't see boiling hurting the force very much.

It's true that you have magnets in your stirplate that won't be affected by boiling because you don't boil the plate, but the stirbar is also a magnet (which is how the other magnets make it spin).

I don't think the stir-bar needs to be magnetized to be picked up by the stirplate.

This is the most interesting thread I have ever read on magnets.

thanks for all the feedback!

Probably not, but you get a much stronger magnetic coupling - magnet to magnet. FWIW, I boil my stir bar all the time. How much damage can be caused at 212? Besides that, they are cheap enough to throw out if they do get demagnetized. But in actuality, I will lose it WAY before it ever becomes demagnetized. That's why I buy them a bunch at a time.

That's true. I know that all of my stirbars are magnets themselves though. May be true for yours as well, but, as some others said, it probably doesn't matter because it is a slow process.

That might be true, for a while, but do you really want to risk turning your stir-bar into a brew-wrecking missile from hell because you decoupled the magnetic link between the stir-bar and plate?
