The average Hackaday reader may know, at least in an academic sense, what a magnetic field looks like. But since the gel-like spheres in our skulls can only perceive a small part of the EM spectrum, we have to look at those textbook diagrams on the surface.That is, unless you have One of these beautiful magnetic field visualizers developed by [Dr.Stone].
Using the XMC1100 microcontroller development board and the TLV49 3D magnetic sensor, the device can track the magnetic pole of the magnet in real time and generate an approximate value of the field lines on its electronic paper display. The relative field strength is indicated by the size of the visualization, which allows the user to easily compare multiple magnets. By the way, [Dr.Stone] Note that the current version of the hardware and software can only handle one magnet at a time; visualizing complex magnetic fields and more than two magnetic poles requires a series of sensors and may require a more powerful processor.
you need To visualize the field lines around the magnet? Maybe not. But being able to quickly understand the strength of a magnet and determine the position of its magnetic poles will definitely come in handy.We want to see [Dr.Stone] Take the project to the next stage and turn it into a handheld device for ease of use on the workbench. Compared to some of the methods we have seen before to visualize the magnetic field, it will be much less, but if you only worry about the field strength, you can say that there is a more direct way to display it.
