Magnetic stirrer
It is suitable for experimental fields such as biology, physics and chemistry, cosmetics, health care products, food, reagents, etc. The magnetic stirrer utilizes the characteristic of the same-sex repulsion of magnetic substances, and drives the magnetic stirrer to rotate by constantly changing the polarity of the two ends of the base, and drives the sample to rotate through the rotation of the magnetic stirrer, so that the sample is evenly mixed! It is an experimental equipment for liquid mixing and stirring. product concept

Difference Between Electric Stirrer and Magnetic Stirrer
The essence of the electromagnetic stirrer is to strengthen the movement of molten steel by means of the electromagnetic force induced in the liquid phase cavity of the slab. Magnetic stirrer is a laboratory instrument for liquid mixing, mainly used for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixture. Its basic principle is to use the principle of the same-sex repulsion and opposite-sex attraction of the magnetic field, and use the magnetic field to push the magnetic stirrer placed in the container to perform circular rotation, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, it can heat and control the sample temperature according to the specific experimental requirements, maintain the temperature conditions required by the experimental conditions, and ensure that the liquid mixing meets the experimental requirements. Specifically, the alternating characteristics of the stirrer excitation: the radiation of the wave particles penetrates into the molten steel of the slab, and a current is induced in it, and the induced current interacts with the local magnetic field to generate an electromagnetic force, which is a body force. On the molten steel volume element, it can promote the movement of molten steel.
The electric stirrer uses a motor to connect the stirring rod to stir in the container, while the electromagnetic stirrer uses the motor to drive the magnet inside the body, and the magnet drives the magnetic stirrer in the container to perform the stirring action.
