How photons are responsible for 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.
Why are photons virtual?
These photons are “virtual”; that is, they cannot be seen or detected in any way because their existence violates the conservation of energy and momentum. The photon exchange is merely the “force” of the interaction, because interacting particles change their speed and direction of travel as they release…
Which is the electromagnetic attractive force that acts between particles of different substances?
An intermolecular force (IMF) (or secondary force) is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions.
What is responsible for creating electromagnetic force?
Electromagnetic Force 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”.
What is the electromagnetic force responsible for?
The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.
Do virtual photons have momentum?
You say virtual photon caries only momentum and changes only momentum of the particle. Momentum p of electron is v∗m. Energy of moving electron is E=mc2√1−v2/c2, which means, changing velocity = changing energy.
What is a virtual photon?
Photons mediate electromagnetic interactions between particles in quantum electrodynamics. An isolated electron at a constant velocity cannot emit or absorb a real photon; doing so would violate conservation of energy and momentum. Instead, virtual photons can transfer momentum between two charged particles.
Why do virtual photons behave as if they have negative mass?
It would in fact move the particle in the opposite direction, causing the attraction referred to. Now imagine that somehow the fact that the charge is opposite causes the virtual photon to behave as if the particle had negative mass. Another commentator: Virtual photons are called “virtual” photons for a reason.
How do photons interact with each other?
They only interact with charged particles, and not with each other. That’s why photons don’t interact with magnetic fields — the photons which make up the magnetic field are not charged so other photons cannot interact with them.
How do virtual photons transfer momentum?
Instead, virtual photons can transfer momentum between two charged particles. This exchange of virtual photons, for example, generates the Coulomb force. The commentary on this topic in online forums is a wild ride from the early 2000’s to 2015 [1].
