Graphite electromagnetic induction

Click For Summary
SUMMARY

The discussion centers on the electromagnetic induction properties of graphite when subjected to a varying magnetic field. Participants suggest conducting an experiment using a voltmeter and a magnet to measure voltage differences along a spiral graphite drawing on a wall. However, it is noted that graphite's limitations in high-frequency applications may affect the results due to magnetic saturation. The saturation parameter of graphite is crucial for understanding its behavior in such experiments.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with graphite's electrical properties
  • Knowledge of magnetic saturation concepts
  • Experience with basic experimental setups involving voltmeters and magnets
NEXT STEPS
  • Research the effects of magnetic saturation on graphite at varying frequencies
  • Learn about the principles of electromagnetic induction in conductive materials
  • Explore experimental techniques for measuring voltage differences in conductive drawings
  • Investigate the limitations of graphite in high-frequency applications
USEFUL FOR

Physicists, materials scientists, and educators interested in electromagnetic induction experiments and the properties of conductive materials like graphite.

since graphite conducts. if spiral shape is drawn with pencil on the wall (thick , dark lines)
will a voltage difference appear between inner and outer end of the spiral when a varying magnetic field is switched on, normal to wall

Sounds like a fun experiment. Perhaps you should take a magnet, a voltmeter, and try it out.
