Neodymium magnet toys are toys consisting of or incorporating neodymium magnets. Most commonly they are magnetic construction sets or magnetic sphere building toys. They are sometimes marketed as executive toys. The first neodymium magnet toy set was Neocube, developed by Chris Reda from Pittsburgh, United States in 2008. He got the idea after using magnets to keep track of his pens.[1] The first person to use magnetic dots to build complicated geometric shapes was Janos Szaki,[2] a programming analyst and mathematician from Hungary. Similar products are available under several brand names such as Nanodots, Buckyballs, Desk Dots, and Zen Magnets.
The swallowing of small magnetic toy components such as those in these magnetic toys can result in intestinal injury requiring surgery, or in rare cases even result in death because the components attract each other strongly.[3][4]
