    If you buy the largest commonly available nail, it will be soft iron (untempered). This is a good choice to make an electromagnet, for example.

    One force is static electricity - different charges on the plastic rod and the paper attract each other and the other force is ferromagnetism - the pull of a magnetic field on certain metals, particularly iron.
