The study of this phenomenon began in the 20th century with the work of Alfvén and Hartmann, and has been widely used in industry, metallurgy, and mining, as well as in academia, in the study of nanofluids and gas-insulated electrical equipment. Because it is based on the NavierStokes equation and Maxwell's equations, the MHD phenomenon does not have an analytical solution, thus making it difficult to teach. In this context, an MHD Teaching Bench was developed, with a tool to simulate and demonstrate the behavior of magnetohydrodynamics in a more playful way for students and teachers. Thus, the bench was divided into two different systems. The first is the hydraulic system, consisting of an acrylic duct responsible for the flow of the conductive fluid to be studied, and two 1.4T neodymium magnets positioned on the sides of the duct, thus generating an external magnetic field to interact with the fluid. The system also consists of a water pump for pumping the fluid. The second system on the bench is the electronic system, consisting of four sensors, two flow sensors for measuring speed, and two Hall effect sensors, responsible for measuring the variation in magnetic flux density. These sensors are connected to an ESP-32, which uses IoT (Internet of Things) technology to display the dataread by the sensors on a dashboard, updated in real time, with theaim of demonstrating MHD behavior in a more practical way. In order to validate the operation of the bench, experiments were carried out with two different solutions, using NaCl in one and CH3COONa in the other. Computational simulations were also performed using the Finite Volume Method in OpenFoam software to compare the magnetic flux velocity and density data obtained during the bench experiments. The results obtained showed that the MHD Teaching Bench is capable of representing the phenomenon of agnetohydrodynamics in a more didactic way, thusenabling its use as a teaching tool.Acesso AbertoMagnetohidrodinâmicaSimulação ComputacionalVolumes FinitosMagnetohydrodynamicsComputational SimulationFinite VolumesCNPQ::ENGENHARIAS::ENGENHARIA ELETRICATrabalho de Curso - Graduação - Monografia
