Pseudo magnetic monopoles made from a plurality of building blocks, each having one outer surface that is substantially a north magnetic pole and an opposing outer surface that is substantially a south magnetic pole. The building blocks are assembled to form a hollow object having an inner surface and an outer surface, with all of the north or south poles of the building blocks facing outwardly, such that entire outer surface of the object is substantially either north or south. The building blocks may be magnetized before or after they are assembled to form the hollow object. The hollow object may be a sphere. The building blocks may have tapered side surfaces to minimize gaps between the building blocks when they are assembled to form the hollow object. A plurality of the objects may be provided in kit form as a teaching tool.
