Significance of the Dual Electromagnetic Tensor …

WebThe stress-energy tensor is conserved automatically as a consequence of the geometry of spacetime. A second fundamental but perhaps less well known feature of general relativity is that when the Einstein ﬁeld equations are combined with the singly contracted Riemannian Bianchi identity one obtains a wave equation for the rank three tensor Hλ WebThe most common description of the electromagnetic field uses two three-dimensional vector fields called the electric field and the magnetic field. These vector fields each have a value defined at every point of space and time and are thus often regarded as functions of the space and time coordinates. As such, they are often written as E(x, y ...

WebHere is a brief history of tensors and tensor products. Tensor comes from the Latin tendere, which means \to stretch." In 1822 Cauchy introduced the Cauchy stress tensor in continuum mechanics, and in 1861 Riemann created the Riemann curvature tensor in geometry, but they did not use those names. In 1884, Gibbs [6, Chap. 3] introduced tensor WebThis means that the E-field cannot be a Lorentz vector. We need to put the Electric and Magnetic fields together into one (tensor) object to properly handle Lorentz transformations and to write our equations in a covariant way.

The Field Strength Tensor and Transformation Law for the Electromagnetic Field Last time, we realised that the scalar and vector potentials can be put together into a 4-vector A as A0 = =c, A1 ;2 3 = A x;y;z. However, the electric and magnetic elds are six objects and it’s probably not obvious how these can be put into a relativistic context.

It's not true for a general antisymmetric tensor. The equation you write is a bianchi identity, d ( d A) = 0. . This is true only because F is of the form d A (an exterior derivative).
