Question

The dipole moment per unit volume is called?

Answer 1

In electromagnetism, there are two sorts of dipoles: an electrical dipole deals with the separation of the positive and negative charges found in any electromagnetic system. An easy example of this technique may be a pair of electrical charges of equal magnitude but opposite signs separated by some typically small distance.

Complete answer:
The dipole moment per unit volume is named polarization. The electrical moment induced per unit volume of the dielectric material is named the electric polarization of the dielectric.The SI unit of the measure is coulombs which are per square meter, and also polarization density which is represented by a vector $P$.

The polarization of a medium $P$ gives the electrical moment per unit volume of the material; it's expressed in units of coulombs per meter squared. When a dielectric is placed in an electrical field, it acquires a polarization that depends on the sector.

Electric dipole moments for an electrical dipole are often defined because of the magnitude of either of the fees and therefore the distance by which they're separated from one another. The SI unit of electrical moment is coulomb-meter (Cm) while the C.G.S unit of electrical moment is debye.

Hence, the dipole moment per unit volume is called polarization.

Note: When an object becomes polarized, its center of charge becomes separated from its center of charge. Overall, there are even as many positive charges as negative charges; the thing features a balance of charges and is therefore neutral.
