    Dude, thanks for sharing this invaluable information about magnetic stuff and levitation!

    Hello. Is IT possible to detekted North or Southpol from the magnet. Please help.

      Hello Davide
      Yes, of course you can identify the poles using any magnetometer, but there are also simpler ways.
      You may use a single Hall effect sensor just like in my video ua-cam.com/video/gMpVIo-5q-I/v-deo.html from 0:20 to 0:32, where I identify the poles of the base magnets and measure their strength. In the sensor's datasheet it is clearly indicated the polarity (deviation from midpoint) of the output signal in relation to the orientation of the magnetic field.
      If your magnets can be suspended with their poles in (more or less) horizontal position, you can tie them with a long string and let them reach equilibrium in the earth's magnetic field. This requires that you are not very close to magnetic materials and you know the direction of North. The pole facing North is by definition the North pole!
      If your magnets are NdFeB and their shape is a disc, just put them upright on a flat surface as if you wanted to let them roll. Most Nd magnets are powerful enough, to orient themselves in the earth's field! Again, the disc face to the North is the north pole!
      If you have a magnet of known polarity, you may take advantage of the fact that north poles are attracted by south poles of other magnets, BUT, be very carefull if your magnets are powerful. Their mutual attraction may be etremely strong, they may slip out of your control and they may smash together or pinch a finger! If two powerful magnets are attached together, it may be very difficult to separate them! I never keep more than one magnet at a time out of their boxes before final installation.
      Good luck
      Nikos

      Thanks but the problem is the distance has to be Grödder so I wanted to use the HCM5883l. do you have an idea ? I've been looking for a solution to my project for a long time. I would like to use it with a microcontroller. I've already done it with a reverb but the distance isn't enough. If you can help I would be very happy. greeting Davide

      Hello Davide
      I looked at the datasheet of the HCM5883L. It is comparable to the HSCDTD008A that I used, but I do not fully understand the question. What is the distance that has to be Grödder? I suppose that a drawing would be very helpfull. Can you provide one along with any detail you consider useful? My email is nikosaravantinos at icloud dot com.
