Question

Write a relation for polarisation $\to P$ of a dielectric material in the presence of an external electric field $\to E$

Open in App

Solution

The relation for polarisation $\to P$ of a dielectric material in the presence of an external electric field $\to E$ is $P = X_{e} E$ Where $X_{e} E$ is a constant characteristic of the dielectric and is known as the electric susceptibility of the dielectric medium

Q. When a dielectric is placed in an electric field, it gets polarised. The electric field in a polarised material is less than the applied field. When a paramagnetic substance is kept in a magnetic field, the field in the substance is more than the applied field. Explain the reason of this opposite behaviour.
