Here, We provided to Electromagnetic Theory Formula Sheet By Fiziks Institute. Electromagnetic theory is a discipline concerned with the study of charges at rest and in motion. Electromagnetic principles are fundamental to the study of electrical engineering and physics. Electromagnetic theory is also indispensable to the understanding, analysis, and design of various electrical, electromechanical, and electronic systems.

Magnetism and electricity were once considered as separate forces. However in the year 1873, Clerk Maxwell, a Scottish physicist developed a unified theory of electromagnetism. Its study deals with how the electrically charged particles interact among themselves and with the magnetic field. The main electromagnetic interactions are provided in the points mentioned below.
- Magnetic poles come in pairs that repel and attract each other, just like electric charges do.
- The force of repulsion or attraction between two electric charges is inversely proportional to the square of the distance between the particles.
- An electric field in motion produces a magnetic field.
- A wire with an electric current produces a magnetic field whose direction depends on the direction of the electric current.

An electromagnetic field (also EM field) is a classical (i.e. non-quantum) field produced by moving electric charges. It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field tensor in quantum electrodynamics. The electromagnetic field propagates at the speed of light (in fact, this field can be identified as light) and interacts with charges and currents. Its quantum counterpart is one of the four fundamental forces of nature (the others are gravitation, the weak interaction and strong interaction.)

The field can be viewed as the combination of an electric field and a magnetic field. The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law. The force created by the electric field is much stronger than the force created by the magnetic field. Free download PDF Electromagnetic Theory Formula Sheet By Fiziks Institute.
From a classical perspective in the history of electromagnetism, the electromagnetic field can be regarded as a smooth, continuous field, propagated in a wavelike manner. By contrast, from the perspective of quantum field theory, this field is seen as quantized; meaning that the free quantum field (i.e. non-interacting field) can be expressed as the Fourier sum of creation and annihilation operators in energy-momentum space while the effects of the interacting quantum field may be analyzed in perturbation theory via the S-matrix with the aid of a whole host of mathematical technologies such as the Dyson series, Wick’s theorem, correlation functions, time-evolution operators, Feynman diagrams, etc. Free download PDF Electromagnetic Theory Formula Sheet By Fiziks Institute.
Note that the quantized field is still spatially continuous; its energy states however are discrete (the field’s energy states must not be confused with its energy values, which are continuous; the quantum field’s creation operators create multiple discrete states of energy called photons.)
