High magnetic fields can levitate diamagnetic substances. Conducting parama
gnetic liquids can be levitated by combining electromagnetic and magnetic f
orces. Some recent examples of magnetic processing are given to enlighten s
ome experimental difficulties related to solidification. Levitation appears
as a particular magnetic processing. There are other concepts to damp conv
ection in magnetic liquids, to modify and orient the solidified microstruct
ure. An exciting perspective is the convection suppression in a magnetic li
quid by using much smaller magnetic forces than the levitation force. (C) 2
