Magnetic levitation is one of the mechanisms that is at the forefront of technology. It is used in its most basic form in educational teaching, where the principles of physics converge that have as their principle electromagnetism and the fields created by existing poles that repel according to a quantity of initial current, giving instructive ideas of how the theoretical formulas work, giving life to a practical visual system. The current use on a large scale are the Maglev trains of Japan or superconductivity, being the realization of the quantum effects visualized at the moment of cooling the sample. The electronic circuit tends to be stable because, when using a high-power current, a Triac is needed to compensate the electrical flow provided by the operational amplifier and, therefore, stabilize with the photodiode when activated with the Led diode. Our purpose is to create a circuit that identifies the values of the electronic components that allow reaching equilibrium, with input and output variables that indicate the position and height of the object to be levitated.
The phenomenon of magnetic fields is affected depending on the polarity, the positive and negative poles will give a response of attraction and repulsion that can be easily observed. Being also important as an educational element where the theory materializes and is observed, which enriches all science. The objective of this work is to create a circuit that allows reaching the balance between the electronic components, making use of the fundamental electronics together with an LDR and a light sensor. Both generate a connection bridge in which the object that levitates to remain in the air fluctuates, achieving the objective of creating a levitator and being able to observe the nature of electronics and electromagnetism as a whole. As a result, it was obtained that there is a difference between the use of basic and advanced electronic circuits, in addition to identifying the variation in the voltage consumption between the coin and the screw, because the more voltage consumption, the greater the length of wave implying that the frequency decreases but the power intensifies. On the other hand, it should be noted that the use of a voltage generator to identify the voltage and power variations that were shown at the time of the different tests.
