There is a process for making spherical metal balls where the metal is suspended in an electromagnetic field while the metal is added then cooled.
At present, the only way to levitate anything is with magnetic levitation. It is probably not a practical way at this point in technology.

As of the present, magnetic levitation trains have had little impact in the past. Only an expansion of the technology will have a significant impact.

Advantages of magnetic levitation for haptic interaction are:6-DOF motion with one moving partNoncontact actuation and sensingHigh control bandwidthsPosition resolution and sensitivity
