## Questions & Answers

**Q: Are these strong magnets? i am not sure, as i try to slowly get to max rpm's and it spins out some of the time.**
A: Not sure your application on why you need max RPM...  I am doing yeast starters for home brew.  For me it works perfectly with a 3000ml beaker.  With yeast I shouldn’t do max RMP with my stir plate.  All I need is slow and steady with a small vortex.
