Hi i am a poor Dutch chemistry student, and i and a other student want to make a couple of magnetic stirrer plate, for home project/study, but the even cost a bout $50 secondhand.
Now i want to make one my self, and have all the parts (about $20 in parts per plate), but only have to decide on the type of Neodymium magnet i should use.
This is the stir bar i gone use.
But i am wondering what the best magnet type would be?
Use 2x round disk type 15x5 and having them facing up and down, and i think having the center of the magnets around the ends of the stir bar.
Or 1x bare type 30x10x5.
And a question, if i would use a longer bar type magnet, could i use longer stir bars later on if i need them, or would 6 disk type magnets work better, paired 30, 45 and 60mm spaced from one and other.
A other question i have about the bar type, am i assuming correct that the poles are on the end of the bars?
