If a dielectric is placed in an electric field, what change of the intensity of the electric field takes place inside the dielectric?

If a conductor is placed in an electric field, what change of the intensity of the electric field take place inside the conductor ?

If an electric dipole is placed in a uniform electric field, it experiences :

Due to polarisation the electric field inside a dielectric is

When a dielectric is placed in an electric field, it gets polarized. The electric field in a polarized 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.
