A changing magnetic field can indeed induce current in wire circles, functioning similarly to an antenna. If points A and B are far apart and only a limited number of photons are emitted, the energy from the light can be consumed in generating currents, potentially preventing the light from reaching point B. This implies that as light travels from stars to Earth, it may lose intensity due to interactions with the medium it traverses. The discussion raises questions about the implications of electromagnetic waves and their effects on light intensity over vast distances. Overall, the phenomenon highlights the complex interplay between electromagnetic fields and light propagation.
