A new method is proposed to generate Earth-bound artificial microgravity in a controlled facility capable of emulating lunar/Martian or microgravity for experiments on passive/reactive catalytic multiphase flows. Its applicability was illustrated for trickle beds where flowing gas and liquid experience artificial microgravity inside the bore of a superconducting magnet generating large gradient magnetic fields to compensate for gravity. Artificial

Strong inhomogeneous magnetic fields using NbTi superconducting solenoid magnet up to 9 Tesla were used to investigate trickle-bed reactor hydrodynamics in emulated Earth-bound artificial micro/macrogravity. This environment was able to modify the apparent gravity for both diamagnetic and paramagnetic materials by means of magnetization body force densities. Body force vectors can be co-linear or antiparallel to the cocurrent two-phase downflow in

Powerful superconducting magnets constitute adequate proxies for generating artificial gravity environments in earthbound experimentations. The application of microgravity or macrogravity conditions could be interesting for the pharmaceutical and medical domains for discovering and identifying new drugs and their actions. In the chemical engineering area, strong inhomogeneous magnetic fields could potentially open up attractive applications. For
