  • Electromagnetism Historical survey Britannica

    Electromagnetism Electromagnetism Historical survey: Electric and magnetic forces have been known since antiquity, but they were regarded as separate phenomena for centuries. Magnetism was studied experimentally at least as early as the 13th century; the properties of the magnetic compass undoubtedly aroused interest in the phenomenon.

    Here subscripts e and m are used to differ between electric and magnetic charges.The definitions for monopoles are of theoretical interest, although real magnetic dipoles can

  • String Theory and Electromagnetism: Super-Speedy Energy

    Discovered in the 19th century, the electromagnetic force (or electromagnetism) is a unification of the electrostatic force and the magnetic force. In the mid-20th century, this force was explained in a frame of quantum mechanics called quantum electrodynamics, or QED. In this frame, the electromagnetic force is transferred by particles of light, called photons. The

    Examples of electromagnetic waves traveling through space independent of matter are radio and television waves, microwaves, infrared rays, visible light, ultraviolet light, X-rays, and gamma rays. All of these waves travel at the same speed—namely, the velocity of light (roughly 300,000 kilometres, or 186,000 miles, per second).

  • Electromagnetic field Wikipedia

    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

    Nov 28, 2011· Electrostatic vs Electromagnetic . Static and dynamic electric fields are very important in the study of the electromagnetic field theory. A magnetic field is caused by a time varying electric field. Electrostatics and electromagnetism are two very important topics discussed in electromagnetic
