The effect of a magnetic field on the interface profile between two non-magnetic liquids, aqueous solutions, and/ or organic liquids (the enhanced Moses effect) was investigated. The observed interface profile is well explained quantitatively by an equation that was derived to minimize the sum of the gravitational potential energy and the magnetic energy. In considering this, it will be seen that the magnitude of the magnetic field effect on the interface profile can be enhanced by preparing two liquids whose densities are very close. This "enhanced Moses effect" is demonstrated practically by using a permanent magnet.
