A magnetic heating stirrer (often called a magnetic stirrer with heating or hot‐plate magnetic stirrer) is a common piece of laboratory equipment used to mix and heat liquids simultaneously — very useful in chemistry, biology, and research labs.
Creates a rotating magnetic field beneath the surface.
A magnetic stir bar (also called a flea) placed inside the liquid rotates with that field.
This rotation stirs the liquid without direct physical contact, forming a vortex for effective mixing.
