PolyMagnets

In the E&M course we learned that there can never be a mono pole of a magnet. We can tell this because of Gauss's law for B-field. But a company has found a way to print different poles on the same surface, they do this by printing what they call "maxels" onto the surface of a magnet. The different applications for these could be magnets that attract to a certain distance and then repel once closer together. They can also make "short-throw" magnets that are extremely strong but only attract a few centimeters from the surface of the magnet. It is hard to explain everything that these magnets and their designs can do so there is a video below about how they are made and what they do.
