To successfully pick up the metal object with the magnet, the student should:

Get a larger magnet with a larger magnetic field.

A larger magnet will generally have a stronger magnetic field and be able to attract the metal object from a greater distance compared to a smaller magnet. The other options are not effective; simply rotating the magnet or using a smaller magnet won't improve the situation.
