Abstract
I point out a confusion that is rather common in optical forces, i.e., that the time average of the Lorentz force on a dipole (for a harmonic time-varying field) is sometimes assumed to be a gradient force that is due to omission of the radiative reaction term in the polarizability of the dipole.Keywords
