A student bought a paperclip holder that is shaped like a U. The student tests their new paper clip holder using both plastic and metal paperclips. WHen the student brings the paper clip holder near the paper clips, only the metal ones move towards the paper clip hold and stick to it. The plastic ones do not move.

What is the student most likely testing?

• if the paper clip holder is magnetic

• if the force of gravity causes different materials to move more

• the effects on the density of objects made from different materials
