What does the electromagnetic force depend on?

What does the electromagnetic force depend on?

The existence of electromagnetic waves depends on the interaction between electric and magnetic fields. Maxwell postulated that a time-varying electric field produces a magnetic field. His theory predicted the existence of electromagnetic waves in which each time-varying field produces the other field.

What is the force carrying particle for the electromagnetic interaction?

The force carrier for the electromagnetic force is the photon. Photons, which are commonly called light waves, and referred to as gamma rays, X-rays, visible light, radio waves, and other names depending on their energy.

What does the electromagnetic force control?

Electromagnetic forces are responsible for the chemical bonds between atoms which create molecules, and intermolecular forces. The electromagnetic force governs all chemical processes, which arise from interactions between the electrons of neighboring atoms.

How is electromagnetic related to special relativity?

The theory of special relativity plays an important role in the modern theory of classical electromagnetism. It gives formulas for how electromagnetic objects, in particular the electric and magnetic fields, are altered under a Lorentz transformation from one inertial frame of reference to another.

How does electromagnetic force create electricity?

The electromagnetic force is one of the four fundamental forces. The electric force acts between all charged particles, whether or not they’re moving. The magnetic force acts between moving charged particles. This means that every charged particle gives off an electric field, whether or not it’s moving.

How do photons carry 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.

Is electromagnetic force carried by photons?

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.

How do photons carry the electromagnetic force?

How relativity is applied and what is its use in electricity?

Electromagnets. Magnetism is a relativistic effect, and if you use electricity you can thank relativity for the fact that generators work at all. The charged particles in the wire are affected by the changing magnetic field, which forces some of them to move and creates the current.

Can electricity exist without magnetism?

Electric fields are generated around particles that bear electric charge. Without the electric field, the magnetic field exists in permanent magnets and electric fields exist in the form of static electricity, in absence of the magnetic field.

Is electricity electromagnetic force?

electromagnetism, science of charge and of the forces and fields associated with charge. Electricity and magnetism are two aspects of electromagnetism. Electricity and magnetism were long thought to be separate forces.

What is the exchange particle responsible for the electromagnetic force?

The photon is the exchange particle responsible for the electromagnetic force. The force between two electrons can be visualized in terms of a Feynman diagram as shown below. The infinite range of the electromagnetic force is owed to the zero rest mass of the photon.

What is an example of electromagnetic force?

The simplest example of electromagnetic forces, the mutual force between two stationary pointcharges, is illustrated in Figure 3.1a. The force is directed along the line joining the two particles, r.Intermsofur(a vector of unit length aligned along r), the force on particle 2 from particle 1 is F(1 2)

What is the force between electrons and photons?

Photon. The force between two electrons can be visualized in terms of a Feynman diagram as shown below. The infinite range of the electromagnetic force is owed to the zero rest mass of the photon. While the photon has zero rest mass, it has finite momentum, exhibits deflection by a gravity field, and can exert a force.

How do you find the force of attraction between two particles?

A particle with charge q 1 exerts a force F12 on a particle with charge q 2 . Coulomb’s law gives this force as F12 = (k e q 1 q 2 /r 122) ( r12 /r 12 ). The constant k e is k e = 9*10 9 Nm 2 /C 2 .
