Increasing the thickness of the wire
Increasing the thickness of the wire

Increasing the number of coils
Increasing the number of coils

Adding batteries to the electromagnet

Answer 1

The variable that does not increase the strength of an electromagnet is "Increasing the distance between the coils." Increasing the distance would actually decrease the strength of the electromagnet. The other options (increasing the thickness of the wire, increasing the number of coils, and adding batteries) would generally increase the strength of the electromagnet.
