Electric field from a dipole
WebUse vectors to map the Electric Field patterns of the dipole in 3D From investigating the Electric Field of a dipole in lecture, you have learned very simple, yet powerful formulas for calculating the E-field of a dipole: Along the dipole axis: And perpendicular to the dipole axis: To calculate the Electric field at any location other than ... WebAn electric dipole in an external electric field is subjected to a torque τ = pE sin θ, where θ is the angle between p and E. The torque tends to align the dipole moment p in the direction of E. The potential energy of the dipole is given by Ue = − pE cos θ, or in vector notation Ue = − p · E. In a nonuniform electric field, the ...
