Magnetic Gravity Compensation [PDF]
Microgravity Science and Technology, 2010 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.
