How Do Magnetic Fields Influence Diamagnetic and Paramagnetic Materials?

Click For Summary
SUMMARY

The discussion centers on the influence of magnetic fields on diamagnetic and paramagnetic materials. When exposed to a magnetic field, diamagnetic materials exhibit dipole alignment opposite to the field direction, while paramagnetic materials align their dipoles in the same direction as the field. The phenomenon of dipole alignment in these materials is not fully understood, prompting a search for factual explanations. Key concepts include the role of screening currents in diamagnetism and the energy reduction associated with dipole alignment in paramagnetism.

When a magnetic field is applied to a diamagnetic, the dipoles align opposite to the direction of the magnetic field. However, when a magnetic field is applied to a paramagnetic, the dipoles align to the same direction of the magnetic field.

My professor mentioned in class that the phenomenon of diamagnetic and paramagnetic dipole alignment is unexplained and challenged us to find some sort of factual backing for our explanation. I am asking for help, for guidance, for any ideas on this phenomenon.

Any suggestions?

When an external field is applied to a diamagnetic substance, screening currents occur to oppose the external field; that is why the induced "dipoles" align opposite to the applied field. Paramagnetic behavior is due to permanent dipoles aligning to the field, reducing the total energy.
