Homework Help: Magnetize water with external electromagnetic field

  1. Jan 20, 2007 #1
    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.
