I have purchased the standard Teflon-jacketed magnets several times
from science equipment suppliers marketing to kids & teachers. They
cost a bit more than they should, but they are well suited to the task
and usually last until I lose them.
I see that a recent catalog from Edmund Scientifics (rarely the
cheapest possible source) has a set of three for $9.95 (part
#E31080-00) as well as a stir bar retriever (part #31081-00) for
another $9.95. They are listed as accessories for Laboratory Magnetic
Stirrer (#E30362-84. I'm sure that they are available elsewhere, as well.
