SUMMARY:

At the beginning of the 19th century, works such as those by Faraday and Maxwell established the rules of classical electromagnetism. Using vector formalism, the set of differential equations composed of Maxwell's equations and Lorentz's law of force established a solid basis for several experiments carried out in their time. At the end of the 19th century, experiments such as the double slit, the photoelectric effect, the Michaelson experiment, among others, brought us to the need for a better theoretical explanation for the results. In the 20th century, Albert Einstein proposed in his works some new postulates and thus built a basis for a "new" physics. Through concepts such as the invariance of the speed of light and the independence of the adopted coordinate system, a theory for gravitation emerges, where we adopt a tensor formalism through which we can observe a series of similarities between the electromagnetic theory and the theory of gravitation. Knowing the main tensors responsible for the description of the electromagnetic and gravitational fields, we will describe some of the main algebraic characteristics, and through this characterization we will classify both the Faraday tensor and the Weyl tensor. We will be particularly concerned with gravitation through the Weyl tensor and the so-called Petrov classification. We will qualitatively discuss this classification and its physical interpretation, and briefly see how it can help us in current experiments proposed by observational cosmology, such as the generation and propagation of gravitational waves, fields generated by massive static and uncharged objects, or with rotation around some axis is loaded and the torsional forces in the so-called tidal effects.
