The given magnet holding force is only a comparative value that was measured in a laboratory in Germany at the Institute of Physics. The actual power depends on several factors, such as:
1. The material to which the magnet will be glued. (the higher the carbon content in the steel, the lower the adhesion force).
2. The smoother the surface, the greater the adhesion of the magnet.
3. The thickness of the metal, the thicker the metal, the more the magnet will attract.
