I used the hard drive magnet from an old PC glued to a fan (pretty standard, I assume) for a stir plate I built. I used a 12V power supply and a rheostat.
Problem is the magnet isn't strong enough to hold my stir bar in place. Even at the lowest speed setting, the bar is routinely thrown off to the side of my flask.
Any advice on a magnet I can add to the existing one to increase the holding power?
