The student tested his theory using electromagnets, an iron bar, and a piece of copper coil.
electromagnets
1 a nuke uses electromagnets so does not fall apart they use it to keep the iron shell on and so it does not fall over and does not explode randomly.
An iron core and copper wire (that is coated with an insulator) are used all the time to make electromagnets.
An iron cannot remove wringles, however, an iron can remove wrinkles. Depending on the fabric or material the article of clothing is made from will determine what setting the iron should be set on. An iron has a metal plate that conducts heat, and in turn when the iron is applied to an article of clothing, this heated plated will remove wrinkles when the iron is moved back and forth across the wrinkled area.
no there is no use of electromagnets in iron box
because when any one gets hurt the iron bits remain on it .
An electromagnet, or any magnet, only attracts certain metals like iron. (Steel is a kind of iron.) If you want to remove, for example, aluminum splinters, you must use another process because aluminum is not attracted to a magnet.

Unlike normal magnets, electromagnets attract just someof the alloys that contain iron, such as steel and iron, but not all of them. Electromagnets do not attract aluminium, copper, titanium,brass, bronze, tin, nickel, platinum, gold, silver, lead or pewter.Contrary to some opinions, electromagnets cannot attract cardboard.See also the related question.
Iron is used for electromagnets.
Electromagnets are used in vending machines to deciever real coins from fake ones. Electromagnets will sort counterfeit money from real money, because most counterfeit money is an iron alloy. Iron is magnetic and gets pulled by the electromagnet, while real coins are not effected.
electromagnets are used in batteries to convert energy into electricity
Iron, Cobalt and Nickel.

They both are strong and are made of iron and steel.
