This creates two centers of equal and opposite charges—what is called a dipole, as illustrated in Figure 18.25. The magnitude of the dipole is called the dipole moment. These two centers of charge will terminate some of the electric field lines coming from a free charge, as on a DNA molecule.
18 Απρ 2024 · Definition. We know well how to deal with single point charges and an infinite charged plan which generates a simple form of an electric field, but of course physical systems rarely behave in such a simple way. What we are going to look at here is a model for two point charges that are equal in magnitude and opposite in sign. The reason this is ...
A dipole is a distance r r from an infinitely-long line of negative charge of density λ λ. The dipole moment p→ p → is parallel to the line of charge. Find the magnitude of the torque on the dipole in terms of r r, p→ p →, and λ λ. The dipole moment is now pointing directly at the line of charge (perpendicular to it).
Describe a permanent dipole; Describe an induced dipole; Define and calculate an electric dipole moment; Explain the physical meaning of the dipole moment
Electric dipole moment definition :-The dipole moment of an electric field is a vector whose magnitude is charge times the separation between two opposite charges. Direction of dipole moment is along the dipole axis from negative charge to positive charge.
The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge. It is a useful concept in atoms and molecules where the effects of charge separation are measurable, but the distances between the charges are ...
