Answer 1

The variable that does not increase the strength of an electromagnet is increasing the distance between the coils. This would typically decrease the strength of the magnetic field produced by the coils. The other options (adding batteries, increasing the number of coils, and increasing the thickness of the wire) would generally contribute to a stronger electromagnet.
