Interactions between polar materials and magnetic field

Click For Summary
SUMMARY

The discussion focuses on the interactions between polar materials, such as water, and electric fields. Polar materials possess permanent dipoles that align when subjected to an electric field, resulting in polarization. Once the electric field is removed, the behavior of these dipoles is questioned, specifically whether they remain aligned or revert to random orientation. The conversation also touches on non-polar materials and their lack of dipole alignment under electric fields, referencing the concept of an electret.

PREREQUISITES
  • Understanding of polar and non-polar materials
  • Knowledge of electric field concepts
  • Familiarity with dipole moments
  • Basic principles of polarization
NEXT STEPS
  • Research the properties of electrets and their applications
  • Explore the effects of electric fields on dipole alignment in various materials
  • Study the differences between polar and non-polar materials in electromagnetic contexts
  • Investigate experimental setups to observe dipole behavior in electric fields
USEFUL FOR

Students and researchers in materials science, physicists studying electromagnetic interactions, and anyone interested in the behavior of polar materials in electric fields.

"interactions between polar materials and electric field"
sorry typing error.polar materials are those who have a permanent dipole ( like water molecules ) but these dipoles doesn't appear on the macroscopic scale due to their random orientation , so what if this polar medium is subjected to some electric field , the dipoles will align them selves and the medium will be polarized to oppose the outward field.

now if the outward field is gone , would the dipoles remain as they are ? and would the dipoles in the medium some up to be significant in the macroscopic scale ? or would the dipoles be randomly oriented again?

and what will happen in the same case but if the material medium was non-polar ?

You can do a simple examination, rub a plastic ruler to your hair and close it to thin dropper water; you can observe the deflection of water column just at closest area.
