The correct evaluation of the student's prediction is:
The student is incorrect because the more distance there is between the magnet and the paperclips, the weaker the magnetic force. This means paperclips W and X should move more than Y and Z.
In summary, the strength of the magnetic force decreases with increasing distance. Therefore, the paperclips that are closer to the magnet (W and X) are likely to experience a stronger magnetic force and move more than those that are farther away (Y and Z).
