Hi

try a simple model from the Application library of a 2 phase flow droplet under gravity load buoyancy forces against viscosity forces, (there are a 2D model somewhere therein, then add a static magnetic field in a second study, but start one by one it's simpler.

Note that you need to couple these two physics as the magnetic field and the fluid will not couple if you do not adapt the mur of your fluids material properties, and also magnetic field action on a moving objects is really a 3D effect so align your B field accordingly to get an effect in the 2D plane if you want to really see something

Good luck
