Please help - how do I magnetize water in test tube with electromagnetic field

Click For Summary
SUMMARY

This discussion centers on the challenge of magnetizing water in a test tube using an electromagnetic field. The user wrapped a test tube with 500 turns of magnetic wire connected to a 122-volt DC current, which allowed iron shavings to be picked up with an iron rod but not with water alone. Key concepts mentioned include paramagnetism, diamagnetism, ferromagnetism, and the Curie Point, emphasizing that water cannot retain a magnetic field once the external field is removed.

PREREQUISITES
  • Understanding of electromagnetic principles, specifically DC circuits.
  • Familiarity with types of magnetism: paramagnetic, diamagnetic, and ferromagnetic.
  • Knowledge of the Curie Point and its implications for ferromagnetic materials.
  • Basic experimental setup involving magnetic fields and conductive materials.
NEXT STEPS
  • Research the properties of paramagnetic and diamagnetic materials.
  • Explore the effects of the Curie Point on different substances.
  • Investigate methods to enhance the magnetic properties of liquids.
  • Learn about the behavior of magnetic fields in relation to conductive materials.
USEFUL FOR

Students in physics or engineering, researchers exploring magnetic properties of liquids, and hobbyists interested in electromagnetic experiments.

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.
