An interlocking toy building block includes a first block body and a first magnet positioned therein a first distance from a first outer surface thereof to provide a first predetermined magnetic polarity to the first outer surface. When the first outer surface is brought into close proximity with a second outer surface of a second block body having a second magnet positioned a second distance therein and exhibiting a second predetermined magnetic polarity opposing the first predetermined magnetic polarity, the first outer surface is configured to mate with the second outer surface in an interlocking position. A potential magnetic force F.sub.m between the pair of magnets is determined by the formulation: F.sub.m=F.sub.o e.sup.−rd where F.sub.o is the initial force (i.e., no separation distance between magnets), and e.sup.−rd is the exponential function of the rate of decay “r” of the magnets and the distance “d” between the magnets.

A building toy and a method of building with it. The toy is designed to be constructed of a rigid and generally non-deformable material such as, but not limited to, wood and particularly hardwood, and is constructed in the fashion of a log-style building toy. The toy utilizes interconnecting notches in its construction, but provides for a variety of specialized pieces which allow for interconnection of parts where there is one notch but not another, as well as the ability to build roofs, floors, and specialty structures such as fireplaces through the use of specialized components. Further, the use of more strongly connecting components allows for stronger structures to be built.

Electrical connectors, electrical modules, and systems are provided. In one aspect, an electrical connector includes a housing defining a side surface, an electrical conductor supported by the housing and including an engagement portion proximate the side surface of the housing. The engagement portion is adapted to engage another electrical conductor of another electrical connector. The connector also includes a magnet supported by the housing proximate the side surface of the housing, a projection extending from the side surface of the housing, and a receptacle defined in the side surface of the housing. In other aspects, an electrical module includes at least one of these electrical connectors. In further aspects, a system includes a plurality of these modules and the modules are selectively couplable together.

A flexible building segment includes a first outer-section, a second outer-section, a central-section, a first ribs-section and a second ribs-section. The first outer-section includes a first magnet embedded therein. The second outer-section includes a second magnet embedded therein. The central-section includes a central magnet embedded therein and at least two central attachment slots at opposite sides thereof. The first ribs-section includes a first flexible portion and respective ribs. The first flexible portion couples the central-section with the first outer-section. The ribs, respective of the first ribs-section, are attached to the first flexible portion and parallel to each other. The second ribs-section includes a second flexible portion and respective ribs. The first flexible portion couples the central-section with the second outer-section. The ribs, respective of the second ribs-section, are attached to the second flexible portion and parallel to each other.
