DMCubing | Magcube School Science: Black Plastic's Effect on Magnetic Pullforce @dmcubing6342 | Uploaded February 2017 | Updated October 2024, 1 hour ago.
Simple video, but I believe, very informative, on recent findings regarding magnetic pullforce influenced by various types of plastics.
I asked a friend of mine, a professor at the University of Sao Paulo, if he could confirm my findings among his colleagues that black plastic reduces magnetic pullforce. The answer is yes!
The materials used in the pigments to dye black plastic contain high enough amounts of iron oxides (ferrite, magnetite) that the black plastic does indeed have conductive properties, which in turn have an effect on magnetic strength. This is something I've suspected for a while now, and with the help of these scientists, it's been proven. So, thank you Joao! I appreciate your contribution to the science of cubing!
