Answer: A

To increase the strength of an electromagnet, use a larger nail to magnify the electromagnet in the field. Iron nails increase the current strength of the magnet, resulting to a stronger electromagnetic field.
Moreover, the use of battery with high voltage and use of more coils of wire around the nail will also increase the strength of an electromagnet.
