Move the magnet closer to the paper clip

Answer 1

To allow the electromagnet to attract paper clip Y, the best change would be to move the magnet closer to the paper clip. This would increase the magnetic force acting on the paper clip, making it more likely to be attracted.

Other options, such as wrapping the coil fewer times or changing the battery, would likely decrease the strength of the electromagnet rather than enhance it.
