Linear electric water pump?

I need to figure a way of moving fluid along a pipe without anything in the water (i.e no mechanical bits) would a coil around the pipe produce any movement?

Measure the conductivity of your sample. I suspect that contamintated with algae it may be conductive enough.

A high field magnet, and a relatively low current might actually work.

Thanks Steve
That is more or less what I guessed so next I guess is to try it.
Thanks for your advice. Also coating iron filings in wax seems another possibility
Thanks Guys

What its for is to gently propel algae (in water) along tubes with minimum disturbance.
Why didn't you put that in the original question?
You could use a slow-moving screw.

If you can suffer iron filings then wax coat them (candle wax will do )and then set up a linear electric motor - look it up.

MHD only works in conductive liquids....

He didn't say what was in the water he wants to pump...

Yes I thought so but if I put (for example) iron filings in the water will it produce a flow or will the filings all cling to sides? Is there anything like that that would not oxidise. What its for is to gently propel algae (in water) along tubes with minimum disturbance. I can retrieve the magnetic element later with magnets
MHD.
Only if the water is conductive.

search peristaltic pump.
