why dipole is used.can u send me the accurate definition of this.if we don't use dipole then what will happen
3Consider a pair of charges a small distance apart ( is the vector joining the negative charge to the positive charge and is illustrated in Figure 3.5 such that we can define
which is called the dipole moment. The resulting dipole potential is
If we assume that tends to zero, we may expand the second term in a Taylor series for small . Thus, we obtain
Hence,
The resulting electric field components are given by evaluating
in spherical coordinates. Hence
Thus, falls off in magnitude like and vanishes when
. The electric field for a dipole is shown in Figure 3.6.
Figure 3.6: The electric field lines for an electric dipole.
Electric dipoles are very important . They exist everywhere around us . The presence of electric dipoles in molecules affect their chemical and physical behaviour . They also find use in antennas.
