Possible reasons why a magnetic stirrer does not move could be: the magnetic bar is not properly placed or is stuck to the sides of the container, the stirrer speed is set too low, the stir plate is not turned on, or the stir bar is not strong enough to be rotated by the magnetic field.

What is used to swirl or mix solutions?
A stir bar or magnetic stirrer is commonly used to swirl or mix solutions in a laboratory setting. The stir bar is placed in the solution and is rotated by a magnetic field produced by the magnetic stirrer, resulting in thorough mixing.
Why must the magnetic stirrer be stopped each time before reading the pH?
The magnetic stirrer must be stopped before reading the pH because the movement of the stir bar can cause fluctuations in the solution that could affect the accuracy of the pH measurement. Stopping the stirrer allows the solution to come to rest, giving a more stable reading of the pH.
What is a stirrer in chemistry?
A stirrer in chemistry is a tool used to mix substances together by creating a swirling motion in a container. It is commonly used in laboratories to ensure homogeneity in solutions and to help facilitate reactions by promoting contact between reagents. Stirrers can be manual or automated and come in various forms, such as magnetic stirrers, overhead stirrers, and stir bars.
Why mixture of solution needs to be stirred for half an hour by using magnetic stirrer?
Stirring a mixture of solution for half an hour using a magnetic stirrer ensures uniform distribution of the components, promotes faster dissolution, and helps achieve a homogeneous solution. This process enhances the reaction kinetics by increasing the contact between the reactants and speeds up the overall reaction.
Why is a stirrer used when determining melting point of a solid?
The stirrer is used to homogenize the sample and his temperature.

What is the function of stirrer?
The function of a stirrer is to agitate liquids for speeding up reactions or improving mixtures. The picture on the left is a magnetic stirrer used with hot plates. The picture on the right is a typical glass stirrer used in beakers or test tubes.
How does a magnetic stirrer work to mix substances in a laboratory setting?
A magnetic stirrer uses a rotating magnetic field to spin a magnetic stir bar placed in a container of liquid. The spinning stir bar creates turbulence in the liquid, causing the substances to mix together evenly.
Why must the magnetic stirrer be stopped each time before reading the pH?
The magnetic stirrer must be stopped before reading the pH because the movement of the stir bar can cause fluctuations in the solution that could affect the accuracy of the pH measurement. Stopping the stirrer allows the solution to come to rest, giving a more stable reading of the pH.
Can you used magnetic stirrer in lead acid battery?
Possibly, however I cannot see any function that it would serve.
What is the working principle of Magnetic stirrer?
A magnetic stirrer is helpful for dissolving solids in liquids. As there are several different appearances, all of them will at least have a base with a speed-controlled spinning magnet inside and an exterior stirring bar. You place the stirring bar into a flask or beaker by tenderly sliding it beside the wall of the container. To avert fracture, don't drop the bar onto the bottom of the container. Place the container on the stirrer base and turn the speed control knob to its lowest set. Use enough speed to start the bar turning in the container. If using exact volumes, as with a volumetric flask, be sure take the measurements before adding the stirring bar.When stirring is finished, keep the stirring bar in the container by draft the liquid into another container. Carefully wash the original container and the stirring bar.

Can you make a back scratcher from a paint stirrer?
An effect back scratcher can be made from a paint stirrer in three ways. 1. Scratch your back with the stirrer without changing it in any way. 2. Attach a soft scratcher (such as a scrubby) to the stirrer. 3. Carve the end of the stirrer into a usable shape.
What does stir in meaning?
What does Stirring mean in science The same thing it means in cooking...stick in a stirrer and move the product around.

How does magnetism cause an object to move?
When a magnetic field interacts with a magnetic object, it can exert a force on the object, causing it to move. This occurs because the magnetic field induces a magnetic force on the object based on the orientation and strength of the magnets involved. The object will move in response to this force, either attracting or repelling depending on the alignment of the magnetic poles.
