In physics, the Moses effect is a phenomenon of deformation of the surface of a diamagnetic liquid by a magnetic field.
[1][2] The effect was named after the biblical figure Moses, inspired by the mythological crossing of the Red Sea in the Old Testament.
[3][4][5] The application of magnetic fields on the order of magnitude of 0.5-1 T results in the formation of the near-surface "well" with a depth of dozens of micrometers.
In contrast, the surface of a paramagnetic liquid is raised by the magnetic field.
The Moses effect enables trapping of floating diamagnetic particles and formation of micro-patterns.
