Abstract

Magnetic gravity compensation in fluids is increasingly popular as a means to achieve low-gravity forphysical and life sciences studies. We explain the basics of the magnetic gravity compensation and analyzeits advantages and drawbacks. The main drawback is the spatial heterogeneity of the residual gravity field.We discuss its causes. Some new results concerning the heterogeneity estimation and measurement arepresented. A review of the existing experimental installations and works involving the magnetic gravitycompensation is given for both physical and life sciences.
