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.
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.
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.
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.

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.
There are three types of polarization in dielectric material, they are electronic polarization, ionic polarization and orientational 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).
Why is polarization important?
Polarization is the separation of charges.
activation polarization is a polarization due to charge transfer kinetics of the electrochemical process involved.
Polarization is a property of transverse waves.
example of polarization
The contraction of any peart of heart in ecg is known as polarization. Eg contraction of atria is known as polarization of atria
Longitudinal waves doesn't exhibit polarization or diffraction; these to features are for transverse waves.
No diffraction grating is not used in 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.
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
Polarization arising from the orientation of molecules which have permanent dipole moments.
It is not due to polarization. Those are two different effects.
Why vertical polarization not working in receiver
Polarization indicates light has transverse waves.
Polarization - album - was created in 1977-01.
Polarization curve is measuring the corrosion rate of the metal with respect to current and voltage.
Many sunglasses make use of the polarization of light to reduce glare.
