Neodymium magnets attracting keys through a hand. The magnets are made from an alloy of neodymium, iron and boron (Nd2.Fe14.B), coated in nickel, also known as NIB magnets. They are extremely powerful permanent magnets. Previously marketed as toys, there has been some safety concern over their sale due to reports of the magnets being swallowed and causing injury.
