How can paramagnetic and diamagnetic material rods be distinguished in...
Hey mate
Paramagnetic compounds (and atoms) are attracted to magnetic fields while diamagnetic compounds (and atoms) are repelled from magnetic fields.
Paramagnetic compounds have unpaired electrons while in diamagnetic compounds the electrons all have paired spins.
Very few individual atoms are paramagnetic since this requires having a half-filled MO. In contrast, nearly all molecules are diamagnetic (O2 is a notable exception). That is, they essentially have all paired electrons in MOs.
See this video of a frog floating in a magnetic field. Why does the frog float? The frog is repelled by the magnetic field since all the molecules that make up the frog (or at least the vast majority of them) are diamagnetic. In addition, the magnet is really strong such that the repulsion of the diamagnetic compounds in the frog is strong enough to overcome gravity.
Hope it helps

Paramagnetic vs Diamagnetic Material Rods in a Magnetic Field
Understanding the differences between paramagnetic and diamagnetic materials when placed in a magnetic field can help distinguish between the two.

Paramagnetic Materials:
- Paramagnetic materials are weakly attracted to magnetic fields.
- When placed in a magnetic field, paramagnetic materials align themselves with the field, causing a slight attraction.
- This alignment is temporary and disappears once the magnetic field is removed.
- Examples of paramagnetic materials include aluminum, platinum, and oxygen.

Diamagnetic Materials:
- Diamagnetic materials are weakly repelled by magnetic fields.
- When placed in a magnetic field, diamagnetic materials align themselves in the opposite direction of the field, causing a slight repulsion.
- This alignment is also temporary and disappears once the magnetic field is removed.
- Examples of diamagnetic materials include copper, bismuth, and water.

Distinguishing in a Magnetic Field:
- To distinguish between paramagnetic and diamagnetic rods in a magnetic field, observe their behavior.
- If the rod is weakly attracted to the magnetic field and aligns with it, it is likely a paramagnetic material.
- If the rod is weakly repelled by the magnetic field and aligns in the opposite direction, it is likely a diamagnetic material.
- By understanding the different responses of paramagnetic and diamagnetic materials to magnetic fields, one can easily distinguish between the two types of rods.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Super magnet The term super magnet is a broad term and encompasses several families of rare-earth magnets that include seventeen elements in the periodic table; namely scandium, yttrium, and the fifteen lanthanides. These elements can be magnetized, but have Curie temperatures below room temperature. This means that in their pure form, their magnetism only appears at low temperatures. However, when they form compounds with transition metals such as iron, nickel, cobalt, etc. Curie temperature rises well above room temperature and they can be used effectively at higher temperatures as well. The main advantage they have over conventional magnets is that their greater strength allows for smaller, lighter magnets to be used. Super magnets are of two categories:(i) Neodymium magnet: These are made from an alloy of neodymium, iron, and boron. This material is currently the strongest known type of permanent magnet. It is typically used in the construction of head actuators in computer hard drives and has many electronic applications, such as electric motors, appliances, and magnetic resonance imaging (MRI).(ii) Samarium-cobalt magnet: These are made from an alloy of samarium and cobalt. This second strongest type of rare Earth magnet is also used in electronic motors, turbo-machinery, and because of its high temperature range tolerance may also have many applications for space travel, such as cryogenics and heat resistant machinery. Rare-earth magnets are extremely brittle and also vulnerable to corrosion, so they are usually plated or coated to protect them from breaking, chipping, or crumbling into powder. Since super magnets are about 10 times stronger than ordinary magnets, safe distance should be maintained otherwise these may damage mechanical watch, CRT monitor, pacemaker, credit cards, magnetically stored media etc. These types of magnets are hazardous for health also. The greater force exerted by rare-earth magnets creates hazards that are not seen with other types of magnet. Magnets larger than a few centimeters are strong enough to cause injuries to body parts pinched between two magnets or a magnet and a metal surface, even causing broken bones. Neodymium permanent magnets lose their magnetism 5% every 100 years. So, in the truest sense Neodymium magnets may be considered as a permanent magnet.Neodymium and Samarium are
