ELECTRIC DIPOLES. In these notes, I write down the electric field of a dipole, and also the net force and the torque on a dipole in the electric field of other charges.

An electric dipole is a +Q and a Q separated by a vector a Very common system, e.g. in atoms and molecules The electric dipole moment is p= Qa pointing from Q to +Q
Definition. A dipole is normally considered as a combination of 2 equal point electric charges, of opposite signs, separated by a small distance. Dipole moment. The dipole moment, measured in coulomb metres, is the product of either charge (or pole) and the distance between them.
1 Σεπ 2005 · Electric Dipole. Let’s consider the simplest multi-charge system: just two oppositely charged particles—a system referred to as an electric dipole. Let’s calculate the electric field anywhere along the x axis (result will actually apply anywhere in the x-z plane for y=0).
Define and calculate an electric dipole moment. Explain the physical meaning of the dipole moment. Earlier we discussed, and calculated, the electric field of a dipole: two equal and opposite charges that are “close” to each other.
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 ...
