The materials would be best to us for the core to make the strongest electromagnetic to pick up the most nails is described below in detail.

Explanation:

Use a couple of wire strip-pers to exclude some centimeters of insulation from every end of the cable. Skillfully cover the cable around the nail. The more cable you enclose around the nail, the more effective your electromagnet will be. Compose certain that you leave sufficient of the cable unwrapped so that you can connect the battery.
