What is a field in quantum mechanics?
In the modern framework of the quantum theory of fields, even without referring to a test particle, a field occupies space, contains energy, and its presence precludes a classical "true vacuum".
What are scalar and vector magnetic fields?
The terms used in this classification are: scalar fields (such as temperature) whose values are given by a single variable at each point of space. vector fields (such as the magnitude and direction of the force at each point in a magnetic field) which are specified by attaching a vector to each point of space.
physics fields of research
What is the scope of research within physics departments?
The scope of research within physics departments expands far beyond what is portrayed in the media, and the sub-fields of physics which enjoy the most public acclaim frankly encompass a minority of active researchers.
What are some modern physics topics?
Modern physics embraces the atom and its component parts, relativity and the interaction of high speeds, cosmology and space exploration, and mesoscopic physics, those pieces of the universe that fall in size between nanometers and micrometers. Some of the fields in modern physics are:

What is a field in physics?
The term fieldin physics generally refers to a quantity that is defined at every point in space and may vary from point to point. Electric field is a vector field, since force is a vector quantity.
What is the physical significance of the concept of electric field?
The true physical significance of the concept of electric field, however , emerges only when we go beyond electrostatics and deal with time- dependent electromagnetic phenomena. Suppose we consider the force between two distant charges q1, q2in accelerated motion.
What is the meaning of φ2 and φ3 in physics?
and φ 2 represent the flux through the surfaces 1 and 2 (of circular cross-section) of the cylinder and φ 3 is the flux through the curved cylindrical part of the closed surface.

What are the benefits of a job in physics?
Career versatility is one of the main benefits of a job in physics. You can take your education (whether it’s a bachelor’s or a doctorate) and apply it towards medicine, communication technology, space exploration, agriculture, manufacturing, transportation, and almost any other sector you can think of.
What is the job description of a physicist?
Theoretical physicists and astronomers may study the nature of time or the origin of the universe. Some physicists design and perform experiments with sophisticated equipment such as particle accelerators, electron microscopes, and lasers. Overview. Jobs. Salaries 23. Physics Teacher

What is the field theory in particle physics?
Written By: Unified field theory,, in particle physics, an attempt to describe all fundamental forces and the relationships between elementary particles in terms of a single theoretical framework. In physics, forces can be described by fields that mediate interactions between separate objects.
