Permanent magnets were made by technology developed at IPMS NASU. On the basis of own methods next models of lifting devices were developed: two cylindrical magnetic circuits in nonmagnetic box, with short magnetic circuits, with conical magnetic circuits and axially symmetric magnetic circuits. It was made a model with two cylindrical magnetic circuits in non-magnetic box. The model was tested on capacity and thermal stability.
