How do hot plates work?
A hot plate produces heat by using electricity, instead of traditional means of producing heat by using fire. How it does this is by running electricity through its heat coils. The heat coils have a relatively high level of electrical resistance.
How do I choose a magnetic stirrer?
The length of the bar should be about equal to the magnet size to avoid spinout. Spinout occurs when the bar loses its coupling with the internal magnet of the stirrer and the bar stops spinning altogether. Stir bars significantly longer than the internal magnet might reduce the max speed the bar may be spun.
