“…This kind of restriction also occurs for magnetic compensation that can only be strictly performed in a space of lower dimensionality than the sample. [11][12][13][14] Depending on the magnetic field configuration, exact compensation can be achieved in a plane, a line, or a point; in a two-dimensional space, exact compensation can be obtained on a point or on a line.…”

“…A small zone at the top of a solenoid exists where the magnetic force reaches one extreme [1,2]. One solution is to improve the uniformity of this force this area [3,4]. To reach these goals we insert superconducting rings in a solenoid, as shown in figure 1.…”

In this paper, we study the magnetic force generated by the combination of a solenoid and a superconducting ring insert. We have focused our study on the uniformity of the magnetic force. We use a genetic algorithm to determine the optimal shape of the superconducting ring. We are able to obtain uniformity of 0.5% variance. We also study the influence of several factors on uniformity, such as the critical current of the coil, the ring, and the size of the working area.

“…Recently, theoretical studies on magnetic levitation of deuterium or water have been published. 20,39 Our team also explored this cylindrical geometry 38,39 in adding centrifugal forces existing in spacecraft. 28 In the present paper, previous works are developed so as to study in detail the possibilities offered by magnetic levitation in two-dimensional ͑2D͒ cylindrical geometry.…”

The development of activities in space and of the corresponding technologies requires research on the behavior of both matter and biological organisms under weightless conditions. Various methods have been invented in order to simulate weightlessness, for example, drop towers, sounding rockets, or parabolic flights. Magnetic field ground-based devices have also been developed. This paper introduces an optimization method of the magnetic field so as to obtain magnetic levitation in a two-dimensional cylindrical geometry.
