SUMMARY

The discussion centers on the relationship between medium polarization and electric field intensity, specifically addressing how the polarization of a medium reduces the electric field within it. When a point charge is introduced into a medium, it induces polarization, which generates an opposing electric field that diminishes the overall electric field intensity according to Coulomb's law. The key takeaway is that higher permittivity in a medium correlates with increased polarization, leading to a reduction in electric field intensity due to the opposing field created by the polarized medium.

When a point charge is put in a medium, it polarizes the medium and thus reduces the total electric field inside the medium... I don't understand why does the electric field reduce when the medium gets polarized...

My question in other words is that, when we look at the coulomb's law, we see that the greater the permittivity is, the less will be the electric field intensity...the greater the permittivity of the medium, the greater is its ability to get polarized... So, why does polarization of the medium reduce the electric field intensity...?

PLEASE, I BADLY NEED YOUR HELP... THANKS

The field produced by the polarized medium is opposite to the external field.
