This paper depicts an overview and special technique for the recognition, detection, and measuring of the quality of magnetic on materials. It is based on the Hall Effect principle of and signal converter. The board is small but it gives good results in addition to ease of use, less cost, and low power. The magnetic field emitted from the material to be checked converted to a visual spectrum. This means that magnetic fields can now be seen in real-time, the magnetic sensors used on the tile are some of the most highly sensitive. Visualizing things that are very difficult to normally seen. Because there is so much around that just cannot easily perceive, and how many more important bits of science we would be able to get done if only could easily see them as naturally as seeing things like a color. Magnetic field detection in an object into a two-dimensional image will make that important and very useful, especially with low cost, power, and easy to use, unlike some costly sensors.
