A dipole consisting of an electron and a proton separated by a distance of 4 × 10 -10 m is situated in an electric field of intensity 3 × 10 -5 NC -1 at an angle of …
WebMagnetic field from a magnetic dipole (continued) That is to say, B from magnetic dipoles looks exactly like E from electric dipoles. We can thus work out forces, torques, energies, and even a lot about magnetostatics in magnetically-polarizable matter in strict analogy with electrostatics. The real-dipole paradigms: +q-q s p = qs a Planar loop I WebApr 5, 2024 · The dipole moment is a vector quantity that characterizes a dipole. The action of the dielectric is determined by the interaction between the electric field and the dipole moment. The atom returns to its original state when the electric field is withdrawn. The time it takes to do so is referred to as the relaxation time; it is an exponential decay.
WebElectric dipole moment occurs when there is a separation of charge. It can occur in electrically neutral molecules with ionic bonds or molecules with covalent bonds. Dipole moments measures the electric polarity of … WebAn electric dipole in a uniform external field experiences a torque given as τ = pE sin θ, where the symbol θ denotes the angle between p and E. The moment of the dipole p …
