Magnetic fields provide an attractive possibility of a tailored flow control for metallurgical and crystal growth processes. The following examples will be presented:

-the application of a specially shaped steady magnetic field in the melt extraction process of thin metallic fibers,
-the control of the flow filling process in the investment casting of aluminum alloys,
-the stabilization of electromagnetically levitated droplets,
-the magnetic field control of the Czochralski growth of single crystals of silicon.
The role of model experiments and the development of velocity measuring techniques for metallic melts will be stressed.
