when a dielectric substance is placed between two oppositely charge plates then each atom or molecule of the substance behave as a dipole and the substance is said to be polarized and this phenomenon is called electric polarization.

What is the difference between electrical polarisation and dielectric polarisation?
in electric polarization ion is formed which have more tendency to form then magnetic polarization . in magnetic polarization just transfer of electron via flux . so the basic reason is that ion has more mobility constant then electron.so electric polarization is more faster then magnetic polarization. ...

What is the IEEE definition for circular polarization?
Here is Wikipedias definition: In electrodynamics, circular polarization of an electromagnetic wave is a polarization where the tip of the electric field vector, at a fixed point in space, describes a circle as time progresses. If the wave is frozen in time the electric field vectors describe a helix along the direction of propagation. Circular polarization is a limiting case of the more general condition of elliptical polarization. ...

Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less. ...

What is the Difference between plane of polarization and plane of vibration?
A plane including the direction of light propagation and the direction of electric field is called the "plane of vibration". The "plane of polarization" is a confinement of the electric/magnetic field vector to a given plane along the direction of propagation. ...

What are the types of polarization in dielectric material?
There are three types of polarization in dielectric material, they are electronic polarization, ionic polarization and orientational polarization. ...
Asked in Electronics Engineering
What is cross polarization?
Cross polarization is the polarization orthogonal to the desired polarization. For instance, if the fields from an antenna are meant to be horizontally polarized, the cross-polarization in this case is vertical polarization. If the polarization is Right Hand Circularly Polarized (RHCP), the cross-polarization is Left Hand Circularly Polarized (LHCP). ...

What is charge polarization?
Charge polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. The slight separation of charge makes one side of the atom somewhat positive and the opposite side somewhat negative. ...

Does a mirror polarize the light?
Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. There are a variety of methods of polarizing light. The four methods are : * Polarization by Transmission * Polarization by Reflection * Polarization by Refraction * Polarization by Scattering ...

What is an isotropic dielectric medium?
A dielectric whose polarization always has a direction that is parallel to the applied electric field, and a magnitude which does not depend on the direction of the electric field. I have unfortunately no example to give you. But some plastics do have properties close to being isotropic dielectric. ...
