Abstract
Steel is responsible for providing resistance to flexotraction to reinforced concrete structures. Steel is responsible for providing reinforced concrete structures with a flexural strength. For this reason, it is important to study its behaviour under different tensile states. This study used measuring equipment that was able to determine variations in magnetic properties of B500-SD steel bars during standard tensile tests. The magnetic field generated by a Helmholtz coil was collected through a secondary circuit. This enables the induced electromotive force to relate with the steel deflection stages when subjected to the tests. Moreover, it was possible to determine the variation of magnetic permeability when submitting 12mm and 16mm diameter bars to different tensile states. This method could prove extremely useful in determining the tensile state of ribbed steel bars that are embedded into the concrete structure.

Steel is responsible for providing resistance to flexotraction to reinforced concrete structures
As we are dealing with steel alloys, with iron as the main component, we will work with ferromagnetic materials that are widely used in engineering because of their high magnetic susceptibilities
The general physical characteristics can be defined in terms of magnetic constants, that is to say, the tensed steel bar varies its magnetic character according to the magnitude and force direction with respect to its limit of elasticity [6]
Summary
Steel is responsible for providing resistance to flexotraction to reinforced concrete structures. Steel is responsible for providing reinforced concrete structures with a flexural strength For this reason, it is important to study its behaviour under different tensile states. Este método puede ser útil para conocer el estado tensional de las barras de acero cuando se encuentran dentro de una estructura de hormigón. INTRODUCTION The reinforced concrete, which is mainly formed by concrete and ribbed steel bars, is one of the most used materials in the construction sector For this reason, it is very important to study its behaviour and its components performance, under different types of stress during the building process [1]. Steel ribbed bars provide reinforced concrete structures with higher flexural strength The study of these materials is crucial to determine the behaviour of structures during the building process [2]. The general physical characteristics can be defined in terms of magnetic constants, that is to say, the tensed steel bar varies its magnetic character according to the magnitude and force direction with respect to its limit of elasticity [6]
