I am looking at making a stir plate. I was going to use a coffee can for the housing. I was going to mount a 120mm fan in side near the top attached to a speed controller and use an old 12volt plug in from a old toy.
I am fine on the construction and electronics part but i am a little confused on the magnet part. I know i want a rare earth magnet but how strong? I would rather not use old hard drive magnets, i want something a little less jury rigged.
Would these work?

Thanks for any opinions and/or help
