The combination of two separated point charges of opposite sign but equal magnitude is called an electric: dipole
Electric charge is a term that is used for the physical property of a matter, It leads the charged matter to experience a force whenever it is placed in an electromagnetic field.
Electric charge can be either positive or negative. Like charges repel each other and unlike charges attract each other.
In the field of electromagnetism, an electric dipole is the separation of the positive and negative charges in an electromagnetic system.
A good example of this system is pair of charges of equal magnitude but opposite sign that is separated by some small distance.
