Usually having a relatively strong magnetic field in water is a big "no no".

The way to prevent this is a electromagnet with an AC signal. And we'd be back to the electric current inside water.

But it might work.
as I said,
'Could be encased in plastic if the 'fear' of metal in the water upsets you'
mix up a little epoxy and drop the sucker into it, protected!!!
I'm not sure what a relatively strong magnetic field is, I was thinking along the lines of using a very small (weak) magnet since the reed switches I have require a minimum of pull to close them.

I assume that when someone says, it might work..within these forums...that should be read as 'it is more than likely that it will work'.
