Permanent magnet-based diamagnetic levitation offers the unique capability of maintaining a levitated object in a static environment at room temperature for an indefinite period. This property enables the creation of unique experimental environments that are fundamentally different from conventional ones under gravity. Furthermore, permanent magnet systems offer the advantage of sustaining stable levitation across a wider range of magnetic fields compared to diamagnetic levitation devices using superconducting magnets. These features allow for phase transitions from liquid to solid or recrystallization of solutes from solution while maintaining the levitated state. In our previous work, 1) we demonstrated several magnet configurations that enable stable levitation of liquids or solids in the narrow valley-shaped regions formed along the edges where cuboid permanent magnets are brought into contact, based on precise calculations of the magnetic field distribution. In this study, we report the discovery of a magnet configuration that dramatically relaxes the conditions required for stable levitation through optimized magnet arrangement.
