Homework Statement

Trying to magnetize water in a test tube so that it will move or pick up iron shaving(s)

Homework Equations

The Attempt at a Solution

Wrapped test tube with magnetic wire (500 turns) wire is connected to DC current of 122 volts. It will pick up iron shavings with an iron rod in the test tube. It will not move or pick up shavings when I put only water in the test tube. How can I magnetize water in a test tube so that it will move or pick up iron shavings

You might start to think about the various types of magnetism: paramagnetic, diamagnetic and ferromagnetic. You might also want to understand the definition of Curie Point in relation to ferromagnetism.

One point, if you are applying a strong magnetic field to the water, how will you know if the iron filings are moving in response to the water or the much larger applied magnetic field.

Hint: Water will not hold a magnetic field for long no matter how strong the applied field. When you switch off the applied magnetic field, the magnetic field generated by the water will decay to zero very quickly.
