To allow the electromagnet to attract paper clip Y, the most effective change would be to:
**Move the magnet closer to the paper clip.**
This is because the strength of the magnetic field decreases with distance, so bringing the electromagnet closer to paper clip Y would increase the magnetic attraction and enable it to lift the paper clip. The other options would not enhance the magnetic attraction.
