Magnetic forces in 2D foams

2005

The asymptotic expression for the ponderomotive force in the magnetic liquid film is derived and a role of the disjoining pressure in 2D magnetic foam formation is considered. New equation for the force balance at the vertex of 2D magnetic foam is proposed and modified Plateau rule for the films is obtained. The theoretical relation for the angle between films fits the experimental data for small magnetic Bond numbers very well.
