c. Doubling the number of times the wire wraps around the nail.
Increasing the number of wire wraps will increase the number of coils and therefore increase the strength of the electromagnet.
Maria makes an electromagnet shown in the figure below. The battery has a voltage of 6.0V, and she uses an iron nail. Which of the following would increase the strength of the magnetic field produced?
a. Reversing the direction of the current flow.
b. Changing the battery to a 3.0V battery.
c. Doubling the number of times the wire wraps around the nail.
d. Replacing the iron nail with one made of plastic.
