I. Introduction
The magnetic field ranges from Earth's natural geomagnetic field to man-made high magnetic fields (HMFs) is playing a pivotal role in various aspects of modern society including navigation, medical application, and scientific research. With the aid of superconducting magnetic-produced large gradient high magnetic field (LGHMF), stable levitation of diamagnetic materials has become available including cells, tissues, and animal models [1]. Thus, the magnetic body force generated by LGHMF can therefore be used to simulate different apparent gravities, which is one of the most promising ground-based tools to realize virtual microgravity conditions on earth [2], [3] . Previous publications show that LGHMF has been widely used to investigate the effects of microgravity on different systems consisting of mice, water drops, insects, plants, frogs, and mammalian cells [2]– [11]. Moreover, our lab has also reported that superconducting magnets-produced LGHMF, affects various aspects of bone cells including survival, morphology, cytoskeleton architecture, and function [12]–[22]. Therefore, diamagnetic levitation could be a suitable ground-based platform to study the gravitational bioeffects.
