A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
Meccano is a brand of model construction system created in 1898 by Frank Hornby in Liverpool, England. The system consists of reusable metal strips, plates, angle girders, wheels, axles and gears, and plastic parts that are connected using nuts and bolts. It enables the building of working models and mechanical devices.
A toy or plaything is an object that is used primarily to provide entertainment. Simple examples include toy blocks, board games, and dolls. Toys are often designed for use by children, although many are designed specifically for adults and pets. Toys can provide utilitarian benefits, including physical exercise, cultural awareness, or academic education. Additionally, utilitarian objects, especially those which are no longer needed for their original purpose, can be used as toys. Examples include children building a fort with empty cereal boxes and tissue paper spools, or a toddler playing with a broken TV remote control. The term "toy" can also be used to refer to utilitarian objects purchased for enjoyment rather than need, or for expensive necessities for which a large fraction of the cost represents its ability to provide enjoyment to the owner, such as luxury cars, high-end motorcycles, gaming computers, and flagship smartphones.
Twistor memory is a form of computer memory formed by wrapping magnetic tape around a current-carrying wire. Operationally, twistor was very similar to core memory. Twistor could also be used to make ROM memories, including a re-programmable form known as piggyback twistor. Both forms were able to be manufactured using automated processes, which was expected to lead to much lower production costs than core-based systems.
Lego Technic is a line of Lego interconnecting plastic rods and parts. The purpose of this series is to create advanced models of working vehicles and machines, compared to the simpler brick-building properties of normal Lego.
Erector Set was a brand of metal toy construction sets which were originally patented by Alfred Carlton Gilbert and first sold by his company, the Mysto Manufacturing Company of New Haven, Connecticut, in 1913. In 1916, the company was reorganized as the A. C. Gilbert Company. The brand continued its independent existence under various corporate ownerships until 2000, when Meccano bought the Erector brand and consolidated its worldwide marketing with its own brand. The coverage here focuses on the historical legacy of the classic Erector Set; for current developments under the "Erector by Meccano" brand name, see the Meccano article.
The Tinkertoy Construction Set—commonly known as Tinkertoy, Tinker Toy, or plural forms thereof—is a construction set for children. It was designed in 1914 and was originally manufactured in Evanston, Illinois, U.S. The brand is now owned by Hasbro.
A billiard ball is a small, hard ball used in cue sports, such as carom billiards, pool, and snooker. The number, type, diameter, color, and pattern of the balls differ depending upon the specific game being played. Various particular ball properties such as hardness, friction coefficient, and resilience are important to accuracy.
STIKFAS are 3.25-inch (8cm) model assembly figures or toys made by Stikfas Pte. Ltd., a company based in Singapore. Once assembled, they can be customized with stickers and pieces from other sets. STIKFAS are designed so that all of the joints are moveable ball/sockets, making them poseable and interchangeable.

A construction set is a set of standardized pieces that allow for the construction of a variety of different models. Construction sets are generally marketed as toys. One very popular brand of construction set toys is Lego.
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth magnets can exceed 1.2 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla.
Geomag, stylized as GEOMAG, is a magnetic construction toy consisting of a collection of bars, each set with a neodymium alloy magnet at both ends, connected by a magnetic plug coated with polypropylene, and nickel-coated metal spheres. These elements interlock using magnetism, allowing for them to be assembled in various ways.
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. Designed to be a cheaper version of the Geomag magnetic construction set, Magnetix's image suffered severely when an early manufacturing defect caused a death. It was sold under various brands after the defect was corrected.
Bayko was a British building model construction toy invented by Charles Plimpton, an early plastics engineer and entrepreneur in Liverpool. First marketed in Britain it was soon exported throughout the British Commonwealth and became a worldwide brand between 1934 and 1967. The name derived from Bakelite, one of the world's first commercial plastics that was originally used to manufacture many of the parts. Bayko was one of the world's earliest plastic toys to be marketed.
Toy safety is the practice of ensuring that toys, especially those made for children, are safe, usually through the application of set safety standards. In many countries, commercial toys must be able to pass safety tests in order to be sold. In the U.S., some toys must meet national standards, while other toys may not have to meet a defined safety standard. In countries where standards exist, they exist in order to prevent accidents, but there have still been some high-profile product recalls after such problems have occurred. The danger is often not due to faulty design; usage and chance both play a role in injury and death incidents as well.
Mega Brands Inc. is a Canadian children's toy company that is currently a wholly owned subsidiary of Mattel. Mega Bloks, a line of construction set toys, is its most popular product. Its other brands include Mega Construx, Mega Puzzles, and Board Dudes. The company distributes a wide range of construction toys, puzzles, and craft-based products.
Wooden toy trains are toy trains that run on a wooden track system with grooves to guide the wheels of the rolling stock. While the trains, tracks and scenery accessories are made mainly of wood, the engines and cars connect to each other using metal hooks or small magnets, and some use plastic wheels mounted on metal axles. Some trains are made to resemble anthropomorphical, fictional, and prototypical railroad equipment.
A Nerf Blaster is a toy gun made by Hasbro that fires foam darts, arrows, discs, or foam balls. “Nerf blaster” or more commonly “Nerf gun” are often used to describe the toy. Nerf blasters are manufactured in multiple forms; the first Nerf blasters emerged in the late 1980s with the release of the Nerf Blast-a-Ball (1989) and the Sharpshooter (1992). Today, Hasbro has produced over twenty unique lines of Nerf-brand blasters, with each line centered on a particular theme or type of ammunition. Hasbro has also produced Nerf blasters based on specific franchises, including Marvel Comics, Star Wars, G.I. Joe, Fortnite, Transformers, Overwatch, Halo Infinite, and Roblox. Nerf blasters are available in several international marketplaces, although some blasters have their names changed or are not sold in certain countries due to laws surrounding toy safety franchises.
A bipolar electric motor is an electric motor with only two poles to its stationary field. They are an example of the simple brushed DC motor, with a commutator. This field may be generated by either a permanent magnet or a field coil.
