Does a Changing Magnetic Field Induce Current in Wire Circles and Affect Light Intensity from Stars to Earth?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of electromagnetic waves and their interaction with wire circles, specifically regarding the induction of current. It is established that an electromagnetic wave of wavelength L can induce a current in wire circles of diameter L/2, effectively functioning as an antenna. The conversation also posits that if the distance between points A and B is significant, the energy from emitted photons may be depleted in generating currents, leading to a reduction in light intensity as it travels from stars to Earth.

PREREQUISITES
  • Understanding of electromagnetic waves and their properties
  • Knowledge of antenna theory and design
  • Familiarity with the concept of photon energy and its interaction with matter
  • Basic principles of current induction in conductive materials
NEXT STEPS
  • Research the principles of electromagnetic wave propagation
  • Study antenna design and its applications in wireless communication
  • Explore the relationship between photon energy and light intensity in astrophysics
  • Investigate the effects of medium on light transmission and intensity loss
USEFUL FOR

Physicists, electrical engineers, astronomy enthusiasts, and anyone interested in the interaction of light and electromagnetic fields.

an electromagnetic wave of wavelength L is emanating from point A to point B. Small circles of wire of diameter L/2 are placed along AB. Will a current be induced in the circles of wire due to the changing magnetic field?

Yeah sure, this is called an antenna.
 
So this means that if A and B are sufficiently apart and only a given amount of photons ar e emitted then the light will never reach B since its energy will have been used up in producing currents?

Does that also mean that light loses a good amount of intensity while coming from stars to Earth as the space is not empty?
