  2. AP Physics C: Electricity and Magnetism - Wikipedia

    en.wikipedia.org/wiki/AP_Physics_C:_Electricity...

    In 1973, this exam was discontinued, and two new exams were created, which each covered Newtonian mechanics and electromagnetism. Before 2006, test-takers paid only once and were given the choice of taking either one or two parts of the Physics C test. This was changed, so now test-takers have to pay twice to take both parts of the AP Physics C ...

  3. Electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Electromagnetism

    The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles.

  4. Maxwell's equations - Wikipedia

    en.wikipedia.org/wiki/Maxwell's_equations

    Some observed electromagnetic phenomena cannot be explained with Maxwell's equations if the source of the electromagnetic fields are the classical distributions of charge and current. These include photon–photon scattering and many other phenomena related to photons or virtual photons , " nonclassical light " and quantum entanglement of ...

  5. Mathematical descriptions of the electromagnetic field

    en.wikipedia.org/wiki/Mathematical_descriptions...

    There are various mathematical descriptions of the electromagnetic field that are used in the study of electromagnetism, one of the four fundamental interactions of nature. In this article, several approaches are discussed, although the equations are in terms of electric and magnetic fields, potentials, and charges with currents, generally ...

  6. Magnetism - Wikipedia

    en.wikipedia.org/wiki/Magnetism

    Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.

  7. Classical electromagnetism and special relativity - Wikipedia

    en.wikipedia.org/wiki/Classical_electromagnetism...

    The theory of special relativity plays an important role in the modern theory of classical electromagnetism.It gives formulas for how electromagnetic objects, in particular the electric and magnetic fields, are altered under a Lorentz transformation from one inertial frame of reference to another.

  8. Electricity and Magnetism (book) - Wikipedia

    en.wikipedia.org/wiki/Electricity_and_Magnetism...

    Electricity and Magnetism is a standard textbook in electromagnetism originally written by Nobel laureate Edward Mills Purcell in 1963. [1] Along with David Griffiths ' Introduction to Electrodynamics , this book is one of the most widely adopted undergraduate textbooks in electromagnetism . [ 2 ]

  9. Electromagnetic field - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_field

    The electromagnetic field is described by classical electrodynamics, an example of a classical field theory. This theory describes many macroscopic physical phenomena accurately. [6] However, it was unable to explain the photoelectric effect and atomic absorption spectroscopy, experiments at the atomic scale.
