Magna-Tiles are a construction toy system. The pieces are plastic tiles of varying shapes that snap together magnetically , allowing users to build various geometric structures. Magna-Tiles were originally developed in Japan , where they were sold under the name Pythagoras .
Magnext is a magnetic construction toy sold by MEGA Brands, consisting of plastic building pieces with embedded neodymium magnets, steel bearing balls, and a variety of additional parts which can be connected together to form anything from skeletal geometric shapes and structures to more robust and functional toys.

Magnetix 'Translucents' 1 Piece Set. Magnetix is a magnetic construction toy that combines plastic building pieces containing embedded neodymium magnets, and steel bearing balls that can be connected to form geometric shapes and structures.
The technique involves pouring a suspension of magnetized ceramic micro-plates. Pores in the plaster mold absorb the liquid from the suspension, solidifying the material from the outside in. The particles are subjected to a strong magnetic field as they solidify that causes them to align in one direction. The field's orientation is changed at ...
This magnetic energy value is about 18 times greater than "ordinary" ferrite magnets by volume and 12 times by mass. This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend ...
The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
Wang tiles (or Wang dominoes), first proposed by mathematician, logician, and philosopher Hao Wang in 1961, is a class of formal systems. They are modeled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them.
