if a strong magnetic field is applied, the molecular magnets set themselves with their lengths almost parallel to it. thus when the resultant magnetic effect is weak,the process is called paramagnetism
paramagnetism is foung in aluminium,manganese and platinum.
Materials that are referred to when discussing paramagnetism are aluminum or platinum.
Gallium is diamagnetic. Note Unlike all the other members of group 13 aluminium exhibits a form of paramagnetism called "Pauli paramagnetism".
give Langevins theory of paramagnetism?
paramagnetism
Yes, Oxygen in its liquid state exhibits paramagnetism.
The paramagnetic value is the number of unpaired electrons in the metal ion.
First make the m.o (molecular orbital) diagram. If the electrons are paired in an orbital then it is diamagnetic . If the electrons are not paired then it is paramagnetic.
diamagnetic has paired electrons as a result it repels for the magnetic field but,paramagnetic has unpaired electrons as a result it attracts tyhe magnetic field
Because in vapour state it exists as S2 molecule and has 2 unpaired electrons in antibonding pi orbital and hence exhibit paramagnetism.
Because in case of liquids and gases there will be more randomness in magnetic moments so that will unable to align in one direction and will start behave as paramagnetism.
A theory which treats a substance as a classical (non-quantum-mechanical) collection of permanent magnetic dipoles with no interactions between them, having a Boltzmann distribution with respect to energy of interaction with an applied field
When we apply external magnetic field, the orbital levels of electrons are rearranged themselves. Final vector sum of the orbital moment along the direction of magnetic field gives van vleck contribution.
