Question

The image shows an electromagnet. How could you increase the strength of an electromagnet? A) Use a larger nail. B) Use a smaller nail. C) Use a battery with less voltage. D) Use fewer coils of wire around the nail.

Answer 1

the answer is A

Step-by-step explanation:

Answer 2

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.
