Electromagnetic tensor

In electromagnetism, the electromagnetic tensor or electromagnetic field tensor (sometimes called the field strength tensor, Faraday tensor or Maxwell bivector) is a tensor that describes the electromagnetic field in spacetime. The EM tensor field was developed by Arnold Sommerfeld after the four-dimensional tensor formulation of special relativity was introduced by Hermann Minkowski. The EM tensor allows related physical laws to be written concisely, and allows for the quantization of the electromagnetic field by a Lagrangian formulation.
