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.

When an electric current flows in a wire, electromagnet creates a magnetic field around the wire. By winding the wire into a coil we can strengthen the magnetic field. Electromagnets are made from coils like this.
