Crystal growth melt flow control using magnetic fields

A contactless control of melt convection is important for many crystal growth technologies. Typically steady magnetic fields are used to damp such flows and, in particular, turbulent fluctuations. Active flow driving forces due to alternating magnetic fields can be of stabilizing character, too.
