  Electromagnetism - Wikipedia, the free encyclopedia
Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess a property known as electric charge, and is in turn affected by the presence and motion of such particles.
An accurate theory of electromagnetism, known as classical electromagnetism, was developed by various physicists over the course of the 19th century, culminating in the work of James Clerk Maxwell, who unified the preceding developments into a single theory and discovered the electromagnetic nature of light.
In classical electromagnetism, the electromagnetic field obeys a set of equations known as Maxwell's equations, and the electromagnetic force is given by the Lorentz force law.

 Classical electromagnetism - Wikipedia, the free encyclopedia
Classical electrodynamics (or classical electromagnetism) is a theory of electromagnetism that was developed over the course of the 19th century, most prominently by James Clerk Maxwell.
It provides an excellent description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible (see quantum electrodynamics).
In the field of particle physics this electromagnetic radiation is the manifestation of the electromagnetic interaction between charged particles.

The term "electromagnetism" comes from the fact that the electric and magnetic fields are closely intertwined, and, under most circumstances, it is impossible to consider the two separately.
The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics and deals with the effects of the electromagnetic field on the dynamic behavior of electrically charged particles.
However, it turns out that the electromagnetic force is the one responsible for practically all the phenomena one encounters in daily life, with the exception of gravity.

Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, composed of the electric field and the magnetic field.
The term "electromagnetism" comes from the fact that the electric and magnetic fields are closely intertwined, and, under many circumstances, it is impossible to consider the two separately.
For instance, a changing magnetic field gives rise to an electric field; this is the phenomenon of electromagnetic induction, which underlies the operation of electrical generators, induction motors, and transformers.

 A VISUAL TOUR OF CLASSICAL ELECTROMAGNETISM
In Maxwell’s theory, electromagnetic fields are the mediators of the interaction between material objects.
Conversely, we see the electromagnetic energy flow back to the charge from the surrounding field when the charge is being accelerating back down the z-axis by the energy released from the field.
Electromagnetic fields are mediators of the interactions between material objects.  The fields transmit stresses through space.  A magnetic  field transmits a tension along itself and a pressure perpendicular to itself.  The magnitude of the tension or pressure transmitted by an magnetic  field  is given by

            A classical physicist, placed inside the compartment, decides then to study the behavior of an electric charge and, verifying that it doesn't emit electromagnetic radiation, he concludes that the acceleration is purely gravitational.

To infer ontological features in the domain of a physical theory from its mathematical structures often requires one to consider an interpretation of the structures which goes beyond that which is necessary to provide an empirically adequate theory.
I undertake this task for a set of mathematical structures of classical electromagnetism known as potentials.
By investigating the role of potentials in the field theory tradition of classical electromagnetism from its origins through to the present, I argue that this position is neither the necessary nor the proper one for interpreting potentials.

because one has to realise that, though electromagnetism is subject dating back 2 centuries ago and firmly established some hundred years ago, there's still a lot going on in research.Also, Good fails in giving more challenging problems, less numerical and more mathematically engaging...
