ResumoWe find large corrections to the $^{17}\mathrm{O}$ magnetic form factor arising from a two-pion exchange three-body force. These corrections are comparable in magnitude to meson exchange current contributions. The phases of the $M1$, $M3$, and $M5$ amplitudes due to the three-body force are favorable for improving agreement between theory and experiment, especially in the region of momentum transfer between 1.5 and 3.0 ${\mathrm{fm}}^{\ensuremath{-}1}$.NUCLEAR REACTIONS $^{17}\mathrm{O}$($e$,$e$); magnetic form factor, theory including higher order effects and three body force effects.
