Two students have two plastic magnets and a cup of paper clips on their table. Student A tries to pick up a paper clip from the table while holding one magnet 10cm above the paper clip. Student B tries to pick up a different paper clip from the table while holding the other magnet 1 cm above the paper clip. What are two questions you would ask to determine which student could pick up the most paper clips?

What factors do you think will determine how many paper clips each student is able to pick up?
