Abstract :
The analysis of the relations of forces which act on a gas bubble rising in magnetic liquid in the presence of a uniform magnetic field is made to explain the deformation mechanism of them. In order to calculate analytically the magnetic forces distribution inside the magnetic liquid, the magnetic field has been evaluated numerically using the 3D-FEM program Opera of Vector Fields. The results are presented in graphical forms.
