The Mysterious Power of Magnetic Energy: Are There Magnetons?

AI Thread Summary
Magnetic energy is generated when an electric current infuses a material, leading to the creation of a magnet. The discussion raises the question of whether "magnetons," theoretical carriers of magnetic energy, exist, but highlights that current physics does not recognize real magnetons. The propagation speed of a magnetic field change is confirmed to be the speed of light, approximately 186,000 miles per second. This speed indicates that changes in the magnetic field are part of electromagnetic waves, which are essentially light. The relationship between electric currents and magnetic fields is central to understanding magnetic energy.

is seems to be generally agreed upon that any "magnet" comes into being because it has been infused by an Electric Current.

so, my question:

so this magnetic energy is imparted to the material by the electric current.

so, then, what is "magnetic energy" ? are there "Magnetons"?
 
Physics news on Phys.org
well, i found some references to "magnetons". but none of the "magnetons" in the Physics lexicon
have anything to do with real "Magnetons", which would be the theoretical carriers of Magnetic Energy.

is the speed of the Magnetic Field still 186,000 miles per second, or is it instantaneous?
 
Theoretical carriers of magnetic energy... that would be photons.

The speed of propagation of changes in the magnetic field is the speed of light, ~186000 mi/s. That's because it is light. Any changing magnetic field also has an electric field component, and this propagation is an electromagnetic wave, or light.
 

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
