How Do Charged Particles Interact Without Physical Contact?

[gaurav pant]

A charge kept in the vicinity of another charge experiences a force without any physical contact how so

 

[dav2008]

Simple answer: Electromagnetic force.

Simple form of complex answer: The electromagnetic force, which is mediated by virtual photons.

If you want a more in-depth answer I'm sure an expert on the subject could expand on the simple answer.

Physics fields are a fundamental concept in the study of electromagnetism. These fields are a way of understanding the forces that exist between charged particles without the need for physical contact. This is known as the principle of action at a distance. Essentially, a charged particle creates an electric field around it, which can interact with other charged particles in its vicinity. This electric field exerts a force on the other charged particle, causing it to experience a push or pull without any physical contact.

This phenomenon can be explained by the concept of electric potential energy. The charged particle creates a potential energy field around it, and when another charged particle enters this field, it experiences a change in its potential energy. This change in potential energy results in a force being exerted on the particle, causing it to move.

The strength of the force between two charged particles is determined by the magnitude and distance between the charges. The closer the charges are, the stronger the force will be. This is because the electric field strength is inversely proportional to the square of the distance between the charges.

In addition to electric fields, there are also magnetic fields that can interact with charged particles. These fields are created by moving charges and can also exert forces on other charged particles. Together, electric and magnetic fields make up the electromagnetic field, which is responsible for many of the interactions and phenomena we observe in the physical world.

In conclusion, physics fields play a crucial role in understanding the forces that exist between charged particles. These fields allow us to explain how a charged particle can experience a force without any physical contact, providing a deeper understanding of the fundamental principles of electromagnetism.
