How do photons mediate electromagnetic force?
The particles that carry that force, called photons, act like love notes. They draw the protons and electrons together. When two electrons, which both have a negative charge, communicate through electromagnetism, the photons act more like hate mail. They push the electrons apart.
How is the electromagnetic force mediated?
The electromagnetic field is mediated by photons (energy quanta). Its range is infinite, the interaction only weakens quadratically with distance due to the area of an expanding virtual sphere.
Do photons mediate magnetism?
The electromagnetic interaction is mediated by the constant exchange of photons from one charged object to another. The magnetic field is really just a classical approximation to the photon-exchange picture.
Do photons carry magnetic force?
Photons do not experience the electromagnetic force themselves, and so they do not interact with each other, but the effects of electromagnetism are produced by the energy and momentum they carry. The photons that carry force are known as ‘virtual’ particles.
Can a photon be deflected by an magnetic field?
Photons do not have any charge, so they are electrically neutral. Hence, photons are not deviated by electric fields and magnetic fields.
How is the electromagnetic force created?
When a conductor is placed in a magnetic field and current flows in the conductor, the magnetic field and the current interact each other to produce force. The force is called “Electromagnetic force”.
Do photos mediate the interaction between electrons and photons?
In this sense photos do mediate the interaction between electrons. In principle electrons also mediate the interaction between photons, though photon-photon scattering is so weak that it has yet to be experimentally observed. Now, from here things get a bit more philosophical and woolly.
What happens to virtual photons in a magnetic field?
The virtual photons are constantly emitted and reabsorbed. A charged object with an electric (and possibly also a magnetic) field is surrounded by an entourage of photons, constantly being emitted and reabsorbed.
What is the relationship between photons and photon exchange?
The photon exchange is merely the “force” of the interaction, because interacting particles change their speed and direction of travel as they release or absorb the energy of a photon. Photons also can be emitted in a free state, in which case they may be observed as light or other forms of electromagnetic radiation.
What is the potential of a photon?
Photons can be emitted by charged particles and those particles propagate to a different point. The way they propagate is parameterzed by a propagator in momentum space that is 1 / q 2 . So a charged particle with charge e emits a photon and and the potential that is set up is e / q 2.
