1. What is the physical phenomenon?Magnetic field-induced surface deformation of diamagnetic liquids
2. What is the origin of name?Inspired by the biblical story of Moses parting the Red Sea
3. Why does the liquid dip when a magnet is near?The liquid is diamagnetic and is repelled by the magnet, while gravity pulls it down and surface tension keeps the surface smooth, so a tiny depression forms.
4. How big is the dip created by the Moses Effect?The dip is very small, only a few tens of micrometers deep, but it can be seen and measured with good equipment.

Diamagnetism: A property of materials that are weakly repelled by an external magnetic field.
