We consider a model dilute ferrofluid with the grains suspended in water (e.g.,γ-Fe2O3) and subject the system to a strong, homogeneous magnetic field directed perpendicular to the surface such that there is chain formation along the field direction. We show that an appropriate impulse initiated at...
