In summary, the behavior of paramagnetic and diamagnetic substances in a non-uniform magnetic field is opposite, with paramagnetic substances being attracted to areas of higher magnetic field strength and diamagnetic substances being repelled. The diagram and labeling may need to be further examined to fully understand the situation.

Revered Members,

Homework Equations




When paramagnetic substances are placed in non uniform magnetic field, they have a tendency to move from weaker to stronger part
Similarly, when diamagnetic substances are placed in non uniform magnetic field, they have a tendency to move from stronger to weaker part.

The Attempt at a Solution


The diagram is wrong because the field is stronger near the poles and weaker away from the poles. But the paramagnetic liquid is moving away from the poles, which is contrary to the property of paramagnetic substance. Similar argument is for diamagnetic liquid too. Members should clarify whether I am right or wrong.

Thank you for bringing up this interesting topic. You are correct in your understanding of the behavior of paramagnetic and diamagnetic substances in a non-uniform magnetic field. Paramagnetic substances have a positive magnetic susceptibility, meaning they are attracted to areas of higher magnetic field strength. Diamagnetic substances have a negative magnetic susceptibility, meaning they are repelled by areas of higher magnetic field strength.

In the diagram, the field is indeed stronger near the poles and weaker away from the poles, as you pointed out. This means that the paramagnetic liquid should be moving towards the poles, while the diamagnetic liquid should be moving away from the poles.

It is possible that there is some error in the diagram or in the labeling of the substances. It would be helpful to have more information or context to fully understand the situation. I would suggest double checking the equations and attempting to replicate the results to confirm the behavior of the substances in the given scenario. Thank you for bringing this to our attention and I hope we can continue to discuss and clarify any further questions or concerns.
 

Related to Paramagnetic and diamagnetic substances

What is the difference between paramagnetic and diamagnetic substances?

Paramagnetic substances are those that are weakly attracted to a magnetic field, while diamagnetic substances are weakly repelled by a magnetic field.

How do paramagnetic and diamagnetic substances behave in a magnetic field?

Paramagnetic substances align their magnetic dipoles with the external magnetic field, causing them to be weakly attracted to the field. Diamagnetic substances, on the other hand, align their dipoles in the opposite direction of the external field, causing them to be weakly repelled by the field.

What causes a substance to be paramagnetic or diamagnetic?

Paramagnetism occurs when a substance has unpaired electrons, which create magnetic dipoles. Diamagnetism occurs when a substance has only paired electrons, resulting in a cancellation of magnetic moments.

What are some examples of paramagnetic substances?

Some common paramagnetic substances include iron, cobalt, and nickel. Other examples include oxygen, copper, and titanium.

Can a substance exhibit both paramagnetic and diamagnetic properties?

Yes, some substances can exhibit both paramagnetic and diamagnetic properties depending on the strength of the external magnetic field. In weaker fields, the substance may be diamagnetic, but in stronger fields, it may exhibit paramagnetic behavior.
