Question

Make a electromagnet using an iron nail ,copper wire and electric cell and cardboard

Answer 1

Use a pair of wire strippers to remove a few centimeters of insulation from each end of the wire. Neatly wrap the wire around the nail. The more wire you wrap around the nail, the stronger your electromagnet will be. Make certain that you leave enough of the wire unwound so that you can attach the battery.Then stick all the things on carboard
