properties of Paramagnetic and diamagnetic substances are???
Answers
Answer:
✨In Diamagnetic materials, there are no atomic dipoles since the resulting magnetic moment of each atom is zero, that is because of the paired electrons and these are repelled by a magnet. Because of this repulsion, the substances in it have a propensity to shift from a strong to a weak section of the external magnetic field in a non-uniform field.
✨The magnetic permeability of a paramagnetic substance is greater than or equal to one.
Paramagnetic materials are attracted towards the electric field weakly.
Temperature is inversely proportional to magnetization in a paramagnetic material.
Answer:
Properties of paramagnetic materials
The unpaired electrons in the atoms of paramagnetic materials are engaged in an incessant dipole moment due to the unpaired electron spin.
Paramagnetic materials move from a weaker region to a stronger region in a nonuniform electric field.
The degree of magnetization of paramagnetic materials in an external electric field (i.e. magnetic susceptibility) is positive and small.
The magnetic permeability of a paramagnetic substance is greater than or equal to one.
Paramagnetic materials are attracted towards the electric field weakly.
Temperature is inversely proportional to magnetization in a paramagnetic material.
When a paramagnetic material is placed in a magnetic field, the dipole moments in it become parallel to the applied magnetic field.
Properties of Diamagnetic Materials
There are no atomic dipoles in diamagnetic materials because the resultant magnetic moment of each atom is zero due to paired electrons.
Diamagnetic materials are repelled by a magnet.
The substances are weakly repelled by the field so in a nonuniform field, these substances have a tendency to move from a strong to a weak part of the external magnetic field.
The intensity of magnetization I is very small, negative and proportional to the magnetizing field.
Magnetic susceptibility is small and negative.
The relative permeability is slightly less than unity.
Diamagnetic materials are independent of temperature. These materials do not obey Curie’s law.
A rod of diamagnetic material comes to rest with its length perpendicular to the direction of the field when it is suspended in a uniform magnetic field because the field is strongest at the poles.
A diamagnetic liquid in a U-Tube depresses in the Limb which is between the poles of a magnet.
The magnetic dipole moment is small and opposite to the magnetic field H.
If a diamagnetic liquid is placed in a watch glass placed on two pole pieces that are quite close to each other then liquid accumulates at sides and shows depression in the middle where the field is strongest.
