What does the magnetic permeability of real materials look like and why?
Dielectric are generally good insulators which implies a large band gap. This means that the valence bands are filled, which in turn means that spins are paired up and orbital angular momentum has ...

Why net force on two oppositely charged charges when submerged in medium of dielectric constant $k$ decreases?
Basic Concept:
When charges are submerged in a dielectric medium (which has a dielectric constant ( k ) greater than 1), the polarization of the dielectric material comes into play. This polarization ...

Why net force on two oppositely charged charges when submerged in medium of dielectric constant $k$ decreases?
The two scenarios mentioned in the question can be re-framed, without any loss of generality, to What happens when a dielectric is placed in an external electric field, say $E_{ext}$.
We must consider ...

Why net force on two oppositely charged charges when submerged in medium of dielectric constant $k$ decreases?
For Case 1 (Dielectric Slab Between Charges): The force increases because the dielectric reduces the effective field in a way that enhances the interaction between opposite charges (attractive force).

Why net force on two oppositely charged charges when submerged in medium of dielectric constant $k$ decreases?
Imagine the dielectric around the submerged objects is composed of many pairs of equal and opposite charges and spaces between the pairs. When polarized, these pairs move apart, but the distance ...
