Magnetic field of a hollow conductor in special circumstances

Click For Summary
SUMMARY

The magnetic flux inside a hollow conductor remains zero, even when the conductor is rotating relative to an observer inside it, due to the equal number of protons and electrons creating a net effect of zero. However, if a direct current (DC) is flowing through the conductor, this introduces a different scenario that may affect the magnetic field. The discussion highlights the implications of rotating charged tubes and the behavior of electrons in relation to the observer.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with the concept of magnetic flux
  • Knowledge of direct current (DC) electricity
  • Basic principles of rotating systems in physics
NEXT STEPS
  • Research the effects of DC current on magnetic fields in conductors
  • Explore the principles of electromagnetic induction
  • Study the behavior of charged particles in rotating frames of reference
  • Investigate the implications of rotating charged tubes on magnetic fields
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism and rotating systems will benefit from this discussion.

I know the magnetic flux inside a hollow conductor is zero. Is this also true if the observer is inside the conductor and the conductor is rotating in relation to the observer so that the electrons are traveling in spirals around the hollow center?

There are the same number of protons as electrons spinning around the observer, so the net effect would be zero.

If you are driving a current in such a way to go around the circular conductor, then that would be a different situation.

Perhaps a charged tube (imbalance of protons and electrons) could be spun?

I forgot to mention that a dc current is flowing through the conductor. Does this change anything?
