Abstract
A magnetic tile construction set is disclosed that may be used to construct extended 3-dimensional structures. In one embodiment, plastic magnets are attached to multiple edges of a lightweight core. The magnets have a width and length comparable to the thickness of the core and a length that is an order of magnitude longer than the thickness of the core. Tiles may be attached to one another at the tile edges through magnetic forces that do not vary by more than a factor of two over the range of angles from 45 degrees to 180 degrees.
