Since the magnets have an inhomogenous field any diamagnetic material is being repelled away from the magnet. As water is diamagnetic, the magnet is able to form a small depression in the water. This depression deflects impinging beams from far away differently than the otherwise flat water surface.

Samarium-Cobalt-Magents?

I am not really sure.
I believe Neodymium-something magnets.
But supposedly up to 1 T magnetic field.
However I am not sure if they indeed reach it.
In principle from the water deflection the force could be calculated and of course then the magnetic field but I am very far away from an "exact" deflection measurement... ;-)

I have to play too with some rare earth magnets. I think I have some neodymium magnets somewhere, careful placed away from each other. ;-)

You're welcome :)
However, the effect is only barely visible, even with those ultra strong permanent magnets.
