Let's say that you have a glass cylindrical chamber, with a carbon electrode at the top and at the bottom. If I connected electricity to the electrodes, and I spun the glass chamber, or somehow spun the water inside in a whirlpool type pattern, would I get some sort of magnetic field. Or, the main question is, can water be used to make an electromagnet, in place of metal coils? I have been trying to come up with a device that can do this, but I am not quite sure how yet. | ||

Certainly. Suppose you had a flexible plastic tube full of water with some salt or vinegar in it to increase the conductivity. Now coil that up. Put an electrode at either end, and apply voltage. The field generated will be limited by several factors. First, magnetic fields are measured in ampere-turns, so the strength of the field will be determined by how many amperes of current you have, and how many turns there are in the coil. But the current will be splitting the molecules of water into hydrogen and oxygen, and much of the energy will go into that process instead of into the magnetic field. The bubbles will limit the conductance of the electrodes by separating the water from the electrodes. The current will be further limited by the resistance of the salt water. If you put a lot of current through the salt water, it will boil. However, I would suspect that a coil of 50 turns, filled with salt water, and attached to a single D cell (1.5 volts), will generate enough of a field to deflect a compass. Let us know how the experiment turns out -- even if you get negative results. | ||

Well it took me a while, but i've done it. I wouldn't recomend this experiment. The magnetic field wasn't very strong, and the electrolysis caused gas pressure. |
