What is the name of the field of force surrounding a charged particle?

The name of the field of force surrounding a charged particle is the electric field. An electric field is created around a charged object, and it exerts a force on other nearby charged particles. The strength and direction of the electric field depend on the amount of charge and the distance from the charged particle.

When another charged object enters this electric field, it experiences a force that can be attractive or repulsive, depending on the nature of the charges (like charges repel and opposite charges attract). The concept of electric fields is fundamental in understanding how charged particles interact with each other, and it plays a crucial role in various physical phenomena, including capacitors, electric circuits, and the behavior of particles in electric fields.

In contrast, a magnetic field is associated with moving charges or magnets and primarily affects moving charges rather than stationary ones. A gravitational field describes the force of gravity exerted by masses, which is distinct from the forces involved with charged particles. An electromagnetic field combines electric and magnetic effects but is not specifically defined as the field surrounding a single charged particle.
