The effect of an external electric field on water

AI Thread Summary
The discussion centers on an experiment investigating how an external electric field affects the deflection of a thin stream of water. The experiment aims to measure the degree of deflection relative to varying voltages applied across electrodes. The participant is seeking information on previous research related to this phenomenon to support their extended essay for the IB diploma program. There is a mention of confusion regarding the influence of the magnetic field, which seems to be a mix-up with the electric field topic. Overall, the focus is on understanding the relationship between electric field strength and water stream deflection.

Hi

If a charged glass rod is held near to a thin strem of water, the strem of water bends.

I have decided to do an experiment which builds on this premise for my extended essay.

My experiment is basically to run a thin stream of water from a burette through an electric field, and see how much the stream of water is deflected when i vary the voltage actross the electrodes.

Basically i hope to find out how the strength of the electric field is affecting the distance the stream of water is deflected, from where it normally would hit, per cm of electric field it passes through.

Does any of you know if similar work have been done, or something else relevant?
(an extended essay is a 4000 word research paper, in which i should be able to complete the lab part in about 5 days.)
the IB diploma programme is about at high scool level.

I'm confused
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
