Answer 1

To attract paper clip Y, the best option would be:

Move the magnet closer to the paper clip

Moving the magnet closer increases the magnetic field strength at the location of the paper clip, which would enhance the attraction. The other options either reduce the strength of the magnet or do not provide a sufficient effect.
