ABSTRACT
Magnetic compensation of gravity has many advantages compared to other ways to access weightlessness, such as unlimited experimentation time, ground-based experiments, and easily adjustable level of simulated gravity. It is the only way to directly compensate gravity at the molecular level, on the ground. Partial gravity compensation allows simulation of the gravity on Moon or Mars. Many experiments in magnetic gravity compensation focus on fluid mechanics, especially on gas bubbles, liquid drops, and diphasic fluids with or without temperature gradient. The strong magnetic field can produce other effects not observed in weightlessness. In order to differentiate between effects of levitation and any other effects of the strong magnetic field, at least two chambers containing the biological samples are usually placed in the magnetic field, one enclosing the point where the sample levitates and another enclosing the geometric center of the solenoid.
