Dipoles can be represented by their “electric dipole vector” (or “electric dipole moment”), p →, defined to point in the direction from the negative charge to the positive charge, with magnitude: p = Q l. Dipoles arise often in nature, for example, a water ... WebSolution Step 1:Torque of the dipole a in uniform electric field. τ ⇀ = p ⇀ × E ⇀ Here, p ⇀ is dipole and E ⇀ is electric field. Dipole: The magnetic dipole moment is the product of pole strength and magnetic length.
