Do magnetic fields affect the speed of light in the Pound-Rebka experiment?

Click For Summary
SUMMARY

The discussion centers on the relationship between magnetic fields and the speed of light, specifically in the context of the Pound-Rebka experiment. Participants explore whether light experiences a shift when transitioning between different magnetic field strengths, particularly in a 1.5 T magnetic field. It is concluded that photons do not interact with magnetic fields directly, thus no measurable shift in light speed occurs due to magnetic fields. However, the concept of energy density in magnetic fields potentially influencing gravitational fields is raised as a point of interest.

PREREQUISITES
  • Understanding of the Pound-Rebka experiment and its implications on gravitational redshift.
  • Knowledge of electromagnetic theory, particularly the behavior of photons in magnetic fields.
  • Familiarity with concepts of energy density and gravitational fields.
  • Basic principles of special relativity and the constancy of the speed of light.
NEXT STEPS
  • Research the implications of the Pound-Rebka experiment on modern physics.
  • Study the interaction of photons with electromagnetic fields in quantum mechanics.
  • Explore the concept of energy density in magnetic fields and its gravitational effects.
  • Investigate the principles of general relativity as they relate to light propagation in varying gravitational fields.
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the intersection of electromagnetism and relativity.

Do clocks tick at different rates in different magnetic fields .

My watch stopped when I accidentally brought it into a 1.5 T magnetic field :smile:
 
nice , If we try to relate this to the pound-rebka experiment , when they tried to measure the gravitational shift of light , If we wanted to expand this to light traveling from a stronger magnetic field to a weaker one , I don’t think we would measure a shift in the light because photons do not interact with magnetic fields at least i think , But would we measure a shift because the magnetic field has an energy density therefore it would have a gravitational field , so would we then measure a shift in the light .
