Magnetize water with external electromagnetic field

[walela1]

I have created an external electromagnetic field by using DC current connected to magnetic wire that is wrapped around a small test tube. I put water in the test tube. I have increased/decreased the gauge of the wire, increased the volts of the DC current, tried AC current and I still cannot get the test tube of water to move iron shavings. It of course works fine when I put an iron rod in the test tube. Is what I am trying to do impossible? Do I just need to continue to increase the power of the electromagnetic field? If yes, to what? I am currently at 34 volts. Or if I am going about this the wrong way, can you suggest another way for me to try.

It is possible to move iron shavings with an external electromagnetic field. However, it is typically difficult and requires a much higher voltage than what you have tried. You may need to increase the voltage up to 100 volts or more. Additionally, you may need to use an AC current instead of DC. Another approach you could take is to use a neodymium magnet. This type of magnet is much stronger than a simple electromagnet, and can be used to move the iron shavings without the need for a high voltage current.
